The topological insulator Bi 2 Te 3 possesses an extraordinary optoelectronic property for wide-band optoelectronics device applications. In this study, we demonstrate a high-responsivity and self-powered on-chip lithium niobate on (LNOI) waveguide-integrated photodetector array operating at 1550 nm. Enhancement of responsivity is attributed to the decreased /Au contact resistance, which facilitated by electrothermal annealing. post-electrothermal annealed was demonstrated photocurrent response increased four orders magnitude, reaching as high 5.5 µA. It features photoresponsivity 60 mA/W time 10 µs. uniform performance fabricated arrays integrated with 4× multi-mode interference same LNOI photonic chips proves its potential applications in high-efficiency optical communication, computing, large-scale data processing.
