IdealPhotonics' Si avalanche photodetector is a high-gain detector in the visible light band (400-1100nm) based on the avalanche effect of silicon semiconductors. It achieves an internal gain of 10²-10³ times by triggering carrier avalanche multiplication through reverse bias (100-400V), making it suitable for weak light detection and high-speed photon counting.It features ultra-high gain (10²-10³ times) and sub-nanosecond response in the visible light band (400-1100nm), achieving single-photon detection through precise bias control (near breakdown voltage). However, it requires deep cooling to suppress dark counting noise (<100Hz), making it a key sensor for quantum communication and lidar.

IdealPhotonics' InGaAs balanced photodetector, a dual-channel differential detector designed for the 1550nm band, improves the signal-to-noise ratio through balanced reception technology, making it suitable for quantum communication and coherent optical communication systems.Nanosecond-level synchronization response and >40dB common-mode rejection require the integration of a cryogenic amplifier to suppress shot noise.
