Photonic DC and microwave characteristics of AlGaAs/GaAs/InGaAs pseudomorphic MODFET

摘要

In this work, we report photonic microwave characteristics of AlGaAs/GaAs/InGaAs pseudomorphic MODFET controlled by /spl lambda/=0.83 /spl mu/m optical source. With photonic controlled DC and microwave characteristics, we extracted nonlinear equivalent circuit model parameters of the fabricated MODFET, and investigated the physical mechanism of microwave performance improvement in the MODFET.
