Special Issue Information

Dear Colleagues,

Photonic integration appears to be a revolutionary technological breakthrough similar to the one that happened with electronics in the 20th century. It has put photonic technologies on a new, dramatically growing track. The development of ultrasmall and high-bandwidth electro-optic modulators, low-noise frequency synthesizers, chip-scale signal processors with orders-of-magnitude enhanced spectral resolution, plus complete integration of semiconductor-based light sources, modulators, and detectors in a single photonic chip has ushered the creation of multifunctional and reconfigurable photonic integrated circuits (PIC) similar to electronic circuits. PIC provide unparalleled performance in terms of bandwidth, power efficiency, footprint, and cost savings at all levels of the hierarchy, deploying a wealth of photonic integration platforms, spanning from electro-optic boards to silicon photonics, III–V materials, and novel materials.

The possible applications of PIC range from optical communication (including but not limited to free space, 5 and 6G, QKD), microwave photonics, structural health monitoring, optical clocks, optical computers, and emulators to biomedical and agricultural photonics. 

The forecasted market capacity for the PIC in practically all technological areas is expected to exceed USD 1.5 billion by 2023. Some of the key players are Agilent Technologies, Inc. (US), Aifotec AG (Germany), Alcatel-Lucent SA (France), Broadcom Inc. (US), Ciena Corporation (US), CyOptics Inc. (US), EMCORE Corporation (US), Enablence Technologies Inc. (Canada), Finisar Corporation (US), Hewlett-Packard Company (US), Infinera Corporation (US), Intel Corporation (US), JDS Uniphase Corporation (US), Kaiam Corporation (US), and Mellanox Technologies Ltd (US). These players contribute majorly toward market growth. Others (Luxtera Inc. (US), NeoPhotonics Corp (US), Oclaro Inc. (US), OneChip Photonics Inc. (US), TE Connectivity (Switzerland), etc.) contribute nearly 30–35% on the PIC market.

The goal of this Special Issue is to attract contributions from world-leading experts in the area of PIC in an effort to offer an overview of the field with a particular emphasis on major advances and outstanding challenges. The accepted contributions will include visionary works emphasizing state-of-the-art design, technological breakthroughs, experimental verifications, proof-of-concept demonstrations, and industrial applications.

All papers need to present original, previously unpublished work and will be subject to the normal standards and peer-review processes of the journal. Manuscripts must be prepared according to the usual standards for submission to Photonics and uploaded through the MDPI electronic submission system.

This study involves the results of research on short-term and long-term DC-drifts in electro-optical modulators based on annealed proton exchange waveguides in LiNbO3 crystals after wafer pre-annealing. The relaxation time of the DC-drift of the operating point for a short-term drift is measured in minutes, and for a long-term drift it is measured in hours and days. DC-drift was measured by applying bias voltage and changing crystal temperature. The obtained results show significant impact on the stability of operating point in EO-modulators after treatment of defective structure of the near-surface layer of a LiNbO3 crystal. Treatment of the disturbed near-surface layer of a LiNbO3 crystal results in the simultaneous reduction in short-term DC-drift and increase in operation stability of electro-optical modulators during long-term measurement of temperature by activation energy calculation.

This article presents a silicon disk resonator of the whispering-gallery-mode (WGM) type. The calculated Q-factor of the silicon WGM resonator was 107. Two methods of studying the surface roughness of a silicon WGM resonator with a nonlinear profile by means of Helios 650 scanning electron microscope and Bruker atomic force microscope (AFM) are presented. The results obtained by the two methods agreed well with each other. A comparison of the surface roughness values of WGM resonators manufactured using different technological approaches is presented. Based on the obtained data, a preliminary estimated Q-factor calculation of the resonators was performed, which was refined by numerical calculation using the finite-difference time-domain (FDTD) method. The effect of the surface roughness of the resonator on its Q-factor was found. Reducing the surface roughness of the resonator from 30 nm to 1–2 nm led to an increase in its Q-factor from 104 to 107. Full article
