Popis: We present our design and characterization on SPADs and NFADs with InGaAs/GaAsSb Type II SL absorber regions on InP substrates with extended wavelength detection up to 2.4µm wavelengths for single photon counting applications. Packaged devices showed very low variation at −40oC, with ∼100nA dark current at 2 volts below breakdown voltage. The measured DCR was 106 Hz at 2 volts excess bias at 223K.
