All-Silicon Waveguide Photodetection for Low-Bias Power Monitoring and 20-km 28-Gb/s NRZ-OOK Signal Transmission
IEEE Journal of Selected Topics in Quantum Electronics, Volume 24, Issue 2, 2017, Pages 1-7.
We investigate the detection characteristics of a vertical p-n junction embedded waveguide in the low-gain region and strong avalanche gain region. Due to the “L” shape p-n junction and relatively high doping concentration, the photon absorption is enhanced and the working bias is reduced. The detection has linear response to input power ...More
