PD-110 product family is a high-sensitivity PIN Si photodetector with ultra-low-noise high-gain transimpedance amplifier. The photodetector is optimized for efficient homodyne/heterodyne extraction of faint optical signals, enabling low-level optical beat signals and pulse shape detections at frequencies up to 1 GHz. The product family is recommended for applications in quantum metrology and continuous-variable quantum optics, where few photon optical signals are detected and efficiently amplified.
