Popis:	Using type-II GaAs 0.5 Sb 0.5 /In 0.53 Ga 0.47 As 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.
