the present waveguide avalanche photodetector exhibits high responsivities of 66 AW optical power of 29 μW and 125 AW optical power of 14 μW for the wavelength bands of 155 and 195 μm respectively The

The current iteration of the waveguide avalanche photodetector demonstrates notably elevated levels of responsivity at 66 A/W (with an optical power of 2.9 μW) and 125 A/W (with an optical power of 1.4 μW) for the 1.55 and 1.95 μm wavelength bands, respectively. Furthermore, the 3 dB-bandwidth measured at 1.05 GHz is at least three orders of magnitude greater than the high-gain photodetectors based on two-dimensional materials previously reported.
