Special Issue Information
Dear Colleagues,
The field of semiconductor optics is vast and intriguing with its applications in many fields including, but not limited to, energy detection and conversion, optical waveguides, optoelectronics, integrated optics, and optical communications. Moreover, due to the rich tunable and unique electro-optic, thermo-optic, and non-linear optical properties specific to semiconductor materials, cutting-edge, efficient, and low power-consuming optoelectronic, all-optical devices, chemical and biosensors, biomedical imaging and neuro-inspired ultra-fast optical computing devices are suggested. The prospects for these applications are even more exciting with the advent of semiconductor plasmonics, which offer next-generation photonic integrated circuits with ultra-small footprints and high-performance optical detectors.
We are pleased to invite you to submit a manuscript to this Special Issue on “Semiconductor Optics”. This Special Issue aims to collect the latest experimental and theoretical research articles on the electro-optical, thermo-optical, and non-linear properties of semiconductors and their applications. The scope of this Special Issue covers the advances in the field of semiconductor optics.
Original research and review articles are welcome in this Special Issue. Research areas may include (but are not limited to) the following: optoelectronic devices, ultrafast optics, semiconductor plasmonics, photodetectors, non-linear optics, semiconductor lasers, integrated optics, metamaterials, optical spectroscopy, multiphysics modeling of electro-optic, thermo-optic, and non-linear effects.
We look forward to receiving your contributions.

Title: A Reconfigurable 1x2 Photonic Logic Gate Controlled by an Externally Induced Metasurface

Abstract: This work reports the design of a 1x2 photonic logic gate controlled by an electrically controlled metasurface, induced by a rectangular array of points where the refractive index is locally changed through the application of a external bias. The device is simulated by BPM and FDTD algorithms and the structure under evaluation is an amorphous silicon 1x2 MMI, joined to an arrayed MOS structure Al/SiNx/a-Si:H/ITO to be used in active-matrix pixel-fashion to control the output of the gate. MMI couplers, based on self-imaging multimode waveguides, are very compact integrated optical components which can perform many different splitting and recombining functions. A simulation approach, based on the beam propagation algorithm, has been used to produce a large dataset of simulations for a MMI structure under different activation map of the MOS pixels. This dateset has been used for training and testing of a machine learning algorithm for classification of the MMI configuration in terms of binary digital output for a 1x2 logical gate. Also, a statistical analysis has been produced, targeting the definition of the most incident activated pixel for each logic gate operation. An optimal configuration is proposed and applied to demonstrate the operation of a 4-bit shift register. This proof of concept paves the way to a more complex device class, supporting the recent advances in programmable photonic integrated circuits.
