High-speed 1.3 μm GaAs internal photoemission resonant cavity enhanced photodetector

Abstract

Photoresponse measurements were carried out in the 1100-1500 nm range by using a single-pass monochromator and a tungsten-halogen projection lamp as the light source. Further, high-speed measurements were made with an optical parametric oscillator (OPO). In general, the results correspond to the first high-speed internal photoemission photodetectors.
