Abstract

Abstract

This work reports a normal incident high speed photodiode operating at two-micron wavelength with InGaAs/GaAsSb type-II multiple quantum wells absorber. A 3dB bandwidth of 25 GHz can be achieved, which is, in our knowledge, the fastest photodiode at 2-micron wavelength.

TuE1.6 - CHARACTERIZATION OF DEEP LEVELS IN INP BASED INGAASBI PHOTODETECTOR

Abstract

Abstract

In this work, low frequency noise spectroscopy and temperature varied photoluminescence was used to characterize the defect levels in InGaAsBi photodetector. Both of these independent techniques have found some deep levels, and some of which are the consistent.
