Apodized Distributed Bragg Reflector (DBR) Bends for Compact cWDM Filter

OSA Advanced Photonics Congress 2021, 2021
We propose apodized DBR bends for a compact (0.0024 mm2/ch) 4 channel cWDM filter. Simulations show -39 dB sidelobe suppression, -32 dB cross-talk, and -0.05 dB insertion loss for an optimized device configuration.

Silicon Photonics Extended-Distributed Bragg Reflector (E-DBR) Lasers for FMCW LiDAR Applications

OSA Optical Sensors and Sensing Congress 2021 (AIS, FTS, HISE, SENSORS, ES), 2021
Silicon Photonics foundry based Extended-Distributed Bragg Reflector (E-DBR) lasers for automotive FMCW LiDAR systems are described, demonstrating record Lorentzian linewidths <240Hz, promising the performance of discrete, commercial, E-DBR lasers, together with low- cost, high-volume, high-reliability manufacturing.

Inherently mode-hop-free distributed bragg reflector (DBR) laser array

IEEE Journal of Selected Topics in Quantum Electronics, 2003
An inherently mode-hop-free tuning of 4.5 nm was achieved with a short-active-region distributed Bragg reflector (DBR) laser. The DBR laser contains no phase-adjustment electrode, which greatly simplifies the tuning. Fast tuning of several nanoseconds and error-free operation for 2.5-Gbit/s direct modulation were also observed.
