We demonstrate a wavelength extended InGaAsBi short-wave infrared photodetector on an InP substrate with the 50% cutoff wavelength up to 2.63μm at room temperature.The moderate growth temperature is applied to balance the Bi incorporation and material quality.Photoluminescence and x-ray diffraction reciprocal space mapping measurements reveal the contents of bismuth and indium in InGaAsBi to be about 2.7% and 76%,respectively.The InGaAsBi detector shows the temperature-insensitive cutoff wavelength with a low coefficient of about 0.96 nm/K.The demonstration indicates the InP-based InGaAsBi material is a promising candidate for wavelength extended short-wave infrared detectors working.
