Analysis of Screening Effects on Terahertz Photoconductive Devices using a Fully-Coupled Multiphysics Approach
Liang Chen, Hakan Bagci
The terahertz current generated by a photoconductive device (PCD) saturates as the power of the input optical pump is increased. This behavior is induced by various screening effec…

Calculation of Photocarrier Generation from Optical Absorption for Time-domain Simulation of Optoelectronic Devices
Liang Chen, Ming Dong, Ran Zhao +1
Photocarrier generation rate in optoelectronic materials is often calculated using the Poynting vector in the frequency domain. However, this approach is not accurate in time-domai…
