High-Efficiency Ultra-Broadband Multi-Tip Edge Couplers for Integration of Distributed Feedback Laser With Silicon-on-Insulator Waveguide
I whakaputaina 2019-01-01Whiwhi kuputuhi katoaA high-efficiency ultra-broadband multi-tip edge coupler based on a silicon-on-insulator platform for direct coupling with the elliptic beam of a distributed feedback laser was developed. The device is composed of a multi-tip section and a combiner section with extra offset regions to reduce the mod...

Ultracompact Silicon Waveguide Bends Designed Using a Particle Swarm Optimization Algorithm
I whakaputaina 2021-01-01Whiwhi kuputuhi katoaIn this study, the trajectory of a 90° bend is divided into two symmetric halves that are mirror images of each other as referenced to the symmetry axis at 45°, and each half is segmented into small curved sections. The bending radius and waveguide width for every section are p...

Optimization for Ultrabroadband Polarization Beam Splitters Using a Genetic Algorithm
I whakaputaina 2019-01-01Whiwhi kuputuhi katoaWe present a design method for a directional coupler-type polarization beam splitter (PBS) for ultrabroadband operation based on a genetic algorithm (GA). The PBS is discretized into short sections, with the geometric parameters of each section optimized using a GA. For PBSs with an operating wavele...
