Low power reconfigurable multilevel nanophotonic devices based on Sn-doped Ge2Sb2Te5 thin films
2022 · ARTICLE · en
In the past years, Ge2Sb2Te5 has been considered a promising functional material for a variety of reconfigurable multilevel devices, including photonic integrated circuits for the post-von Neumann arithmetic processing. However, despite significant advances, it is necessary to reduce the switching energy of Ge2Sb2Te5 for creation of the on-chip low power all-photonic spiking neural networks. The present work focuses on the effect of tin ion implantation on the properties of amorphous Ge2Sb2Te5 thin films, as well as on the performance of Mach-Zehnder interferometers and balanced beam splitters based on them. As a result, Sn-doping accompanied by the formation of weaker bonds in Ge2Sb2Te5 thin films is an efficient approach to significantly reduce the threshold energy of fs-laser initiated phase transitions and change the effective absorption coefficient. The possibility of using the Sn-doped Ge2Sb2Te5 thin films for fully optical multilevel reversible recording between 9 different levels (3 bits) has been demonstrated by experimental measurements of fabricated on-chip balanced beam splitters. The obtained results show that the Sn doping of Ge2Sb2Te5 layer can be used to optimize the properties of the GST225 thin films, in particular to reduce the switching energy. So, it has the potential to improve the characteristics of reconfigurable multilevel nanophotonic devices using the GST225 thin films, including fully non-volatile memory and developed on-chip low power all-photonic circuits for post-von Neumann arithmetic processing. © 2022 Acta Materialia Inc.
Numerical Simulation of a Beam Splitter on a Silicon Chip for the Terahertz Wavelength Range
2022 · BOOK · en
The terahertz range is a modern, actively developing scientific field with numerous applications. Similar to the optical and infrared ranges, photonic integrated circuits (PICs) have also begun to develop in the terahertz range, which have the functionality of devices in free space, but have small dimensions and high efficiency. Presently, there are many different implementations of PIC, however, the idea of terahertz photonic circuits is still young, since there are no realizations of many passive and active elements. In this work, dielectric waveguides and 50/50 beam splitters will be considered, in the implementation of the Y-splitter, a multimode interferometer (MMI) for terahertz radiation, for frequencies of the order of 0.15 THz. The designs considered in this work are not optimal, however, in the future, it is planned to carry out work to improve their key characteristics — reducing losses, increasing bandwidth, decreasing polarization sensitivity
Polycrystalline PbTe:In Films on Amorphous Substrate: Structure and Physical Properties
2022 · ARTICLE · en
Abstract: Polycrystalline PbTe:In films on a polyimide substrate were obtained and investigated. Their structural and transport properties in a wide range of temperatures (10–300 K) were studied. The unique feature of In impurity in PbTe is the stabilization of the Fermi level (pinning effect) that allowed for the preparation polycrystalline films with the same carrier concentration. We found that heat treatment in an argon atmosphere does not change the average grain size and carrier concentration for as-grown films but greatly increases the Hall mobility and the electron mean free path. By comparing the mobility in the bulk and in the film after heat treatment, we extracted the value of the mobility that arises due to scattering at the grain boundary barriers. The ultimate goal of the present study is the development of these films in designing portable uncooled photodetectors for the mid-IR range.
In Situ Monitoring of Layer-by-Layer Assembly Surface Modification of Nanophotonic-Microfluidic Sensor
2022 · ARTICLE · en
ABSTRACT: An elaboration of the photonic based sensors is the most promising direction in modern analytical chemistry from the point of view of real clinical applications. The highest sensitivity is demonstrated by sensors based on photonic integrated circuits (PICs). This type of sensor has been recently successfully combined with microfluidics, which decreased the analyte volume for analysis down to microliter units. The most significant disadvantage regarding these photonic sensors is low specificity. One of the methods that could be useful for such type of problem is the layer by layer (LBL) assembly. The peculiarity of a PIC based sensor is the ability to precisely control surface modification by using measurements of a minimum resonance position shift. The bovine serum albumin (BSA) and tannic acid (TA) molecules were selected for LBL assembly because on one side they form a stable LBL assembly film based on hydrogen bonds, while the other side of both TA and BSA molecules can be used for conjugation with target molecules. A microring resonator (MRR) and a Mach−Zehnder interferometer (MZI) based on a silicon nitride platform combined with a microfluidic system were elaborated and used for monitoring the LBL film assembly. Obtained results have a good correlation with measurements carried out by atom force microscopy. Thus, the ability of using PIC based sensors for in situ control of surface modification was demonstrated and can be considered in point-of-care (POC) devices that have a very good perspective for both early pathological state diagnosis and evaluation of treatment efficiency.
Hybrid nanophotonic–microfluidic sensor for highly sensitive liquid and gas analyses
2022 · ARTICLE · en
Today, a lab-on-a-chip is one of the most promising ways to create sensor devices for gas and liquid analysis for environmental monitoring, early diagnosis, and treatment effectiveness assessment. On the one hand, this requires a large number of measurements and, on the other hand, involves minimum consumption of the test analytes. Combi- nation of highly sensitive photonic integrated circuits (PICs) with microfluidic channels (MFCs) is necessary to solve this problem. In this work, PICs based on a silicon nitride plat- form integrated with MFCs for studying liquids and gases were developed. Different concentrations of isopropanol in de-ionized water were used as the analyte. Based on this, the sensitivity (S) and detection limit (DL) of the analyzed solution were evaluated. Entire system calibration was car- ried out to calculate S and DL, considering experimental and numerical simulation data. This development may be of interest as a promising platform for environmental monitor- ing and realization of point-of-care strategy for biomedical applications. ©
Fully integrated four-channel wavelength-division multiplexed QKD receiver
2022 · ARTICLE · en
Quantum key distribution(QKD) enables secure communication even in the presence ofadvancedquantumcomputers. However, scaling up discrete-variable QKD to high key rates remains a challenge due to the lossy nature ofquantum communication channels and the use of weak coherent states. Photonic integration and massive parallelization are crucial steps toward the goal of high-throughput secret-key distribution. We present a fully integrated photonic chip on silicon nitride featuring a four-channel wavelength-division demultiplexed QKD receiver circuit including state-of- the-art waveguide-integrated superconducting nanowire single-photon detectors (SNSPDs).With a proof-of-principle setup operated at a clock rate of 3.35 GHz, we achieve a total secret-key rate of up to 12.17 Mbit/s at 10 dB channel attenuation with low detector-induced error rates. The QKD receiver architecture is massively scalable and constitutes a foundation for high-rate many-channel QKD transmission. ©

A mmwave rod antenna array compatible with a PCB prototyping technology
2022 · ARTICLE · en
A mmWave communication is becoming a reality. Nowadays, 5G networks are at the stage of commercial implementation while numerous studies around the world are devoted to investigating practical issues of switching to the 6G standard. Next generation communication systems should rely on highly directive transceivers, which potentially suffer from a micromobility issue. In this paper, we report on the design of a mmWave rod antenna array compatible with a PCB prototyping technology. The array makes use of a dielectric multimode interference power splitter integrated with four weakly coupled dielectric rod antennas at its output. It is cheap to fabricate and has a half-power beamwidth of 11° with a corresponding side lobe level of -11 dB at 135 GHz. Thus, the proposed design seems suitable for prototyping mmWave transceivers within lab studies of a micromobility issue in 6G networks. The design is adaptable for high permittivity PCB laminates and, therefore, is potentially compatible with Si platform. All together suggests efficient operation of dielectric rod antenna arrays in the mmWave band and beyond.
Millimeter wave photonic crystal waveguides fabricated via direct machining
2022 · ARTICLE · en
At the moment, millimeter waves attract close attention not only of the scientific community, but also of the communication industry. Number of studies worldwide are currently focused on finding efficient solutions for the transceiver technologies compatible with beamforming and carrier frequencies beyond 100 GHz. It was recently demonstrated that the technology of integrated silicon photonic crystals provides decent propagation loss and low fabrication complexity upon implementation of waveguide components for the submmWave band. In this paper, we report on the millimeter wave photonic crystal waveguides fabricated from high permittivity PCB laminate by the means of direct machining. Inspection of the fabricated waveguide samples reveals no violation of the photonic crystal geometry due to the fabrication tolerances. The photonic crystals are designed for operation at frequencies 140–160 GHz, and we measure the power attenuation coefficient attributed to the waveguide geometry of 0.02 dB/mm at 145 GHz. The design considerations, including justification of the laminate choice, and detailed results of performance tests are presented in the paper.

Mastering of the terahertz frequency band is attractive for numerous practical applications. Fabrication tolerances of widely used computer numerical control machining result in vital increase of input optics losses of active waveguide components at frequencies beyond 1 THz. This issue can be resolved if conventional hollow metallic waveguide technology is replaced by that making use of wave propagation in low-loss dielectric media. In this paper we report on the development of parametric model of a terahertz dielectric rod antenna array. Both analytic and numeric analysis for variety of the antenna array geometries are provided. The developed parametric model can be used to rigidly construct the dielectric rod antenna array with desired beam parameters at any frequency in the terahertz band if the antenna form factor is fixed and Si platform is used. We believe that our findings are of practical importance to terahertz photonics engineers.
