Summary: In this study, a photonic topological insulator strategy based on SSH photonic crystal nanobeam cavities is developed to tailor TESs by manipulating mode coupling in a two-dimensional manner. It is revealed that hole-array based nanobeams in a dielectric membrane can selectively tailor single or double TESs in the telecommunication region by controlling the coupling strength of the adjacent SSH nanobeams in both transverse and axial directions. This finding provides an additional degree of freedom in exploiting the SSH model for integrated topological photonic devices and functionalities on established photonic crystal nanobeam cavity platforms.

Summary: We present the design, fabrication, and experimental characterization of photonic crystal nanobeam cavities with the smallest footprint, largest intrinsic quality factor, and smallest mode volume to date in a monolithic CMOS platform. Two types of cavities with opposite spatial mode symmetries were designed. The nanobeam cavities can be used in reflectionless topologies due to their opposite mode symmetry and evanescent coupling, making them desirable for complex photonic integrated circuits (PICs). The devices were fabricated in a 45 nm monolithic electronics-photonics CMOS platform optimized for silicon photonics (GlobalFoundries 45CLO) and demonstrated quality factors exceeding 100,000, the highest reported among fully cladded PhC nanobeam cavities in any silicon-on-insulator (SOI) platform. The ability of the cavities to confine light into small mode volumes was experimentally confirmed using near-field scanning optical microscopy (NSOM). These cavities are an important step towards realizing ultra-low energy active devices for next-generation integrated optical links beyond current microring resonator-based links and other CMOS PICs.

Summary: In this study, single-port coherent perfect loss (CPL) was numerically demonstrated in a photonic crystal nanobeam using a Fabry-Perot resonator and a perfect magnetic conductor-like boundary. By designing and optimizing a simple Fabry-Perot resonator and coupler in the nanobeam, the researchers were able to achieve CPL with zero reflection in a single port. Adjustment of the lattice constant of the photonic crystal allowed for control of coupling loss in the resonator, ultimately leading to the successful realization of the CPL mode.

Extensive research is being carried out on the various components required for high data throughput using quantum key distribution (QKD) to improve cost-efficiency. A multichannel QKD system for plug-and-play high-bandwidth secure communication at telecom wavelengths has been realized, consisting of a rack-sized multichannel superconducting nanowire single photon detector (SNSPD) system and a highly parallelized time-correlated single photon counting (TCSPC) unit. The system achieves high secret key rates using a coherent-one-way protocol.
