Not Accessible

Your library or personal account may give you access

Abstract

High-speed, high-saturation-current and low capacitance are presented by mushroom dual-absorption partially depleted absorber photodetector. This photodetector achieves 3dB-bandwidth as wide as 37.2GHz, quantum efficiency of 52%, DC saturation current of 550mA and capacitance decreased apparently.
