Abstract :
Resonant cavity enhanced photodetectors based on GaInAsSb have been successfully fabricated and characterised to operate at a resonant wavelength of 2.35 μm at room temperature. The photodetectors show a maximum quantum efficiency of η=63%, a peak responsivity of R=1.21 A/W and a detectivity D of 5.84×109 cm Hz1/2 W-1 at -0.5 V bias at the resonant wavelength
