Abstract

Abstract

Using type-II GaAs0.5Sb0.5/In0.53Ga0.47As hybrid absorber in UTC-PD, significant enhancement (16.7%) in responsivity across 1.31-1.55μm wavelength is achieved. With top-illuminated structure and large active mesa (25μm), such device exhibits >40(33) GHz O-E bandwidths, good responsivities (0.53 (0.7)A/W), and high saturation currents (>5mA) under 1.55 (1.31)μm wavelength.
