摘要	A photodetector with a selective wavelength response is essential for many applications such as imaging, machine vision, and colour identification in particular. A state-of-the-art wavelength selective photodetector is a broadband photodetector mounted with a dichroic prism or an optical filter for selectivity. Furthermore, some of the designs depend on the engineering of the ratio of active material, for example, in triple halide lead perovskite for selective response. Here we numerically propose selective photoresponse using phase -change -material (PCM) antimony trisulfide (Sb2S3) as an active medium. Sb(2)S(3 )shows fast similar to 70 ns and reversible phase transition between its Crystalline (Cry) and Amorphous (Amp) phase with significant contrast in refractive index. The phase transition can be controlled dynamically either by tharmal or optical means. The photo response (R) is optimized for 552 nm (green light) and 691 nm (red light) with R similar to 0.5 A/W and R similar to 0.6 A/W respectively. Moreover, we have shown that by integrating radiative cooling approach one can manage the heat accumulation due to photocurrent or incident light to maintain it's damage threshold. We have realized that one can maintain the PD temperature near to the ambience temperature even at 1000 W/m(2). According to the simulations, the calculated operating temperatures under 1000 W/m(2) with and without radiative cooling are respectively 305 K and 345 K.
