PTS photodetector response test system utilizes microwave photonics techniques for automated measurement of high-speed photodetectors. PTS is fast and fully automated and yields the RF opto-electrical response (S21) of high-speed photodetectors at any operation frequency in specified bands. The system  integrated a low noise, flat spectrum, scannable Modulated light source (up to 5 THz) and a high accurate RF power detector (up to 200 GHz) to measure the RF opto-electrical response (S21) of the photodetectors. The system operates with ease, speed, and precision using a simple graphics user interface via a notebook PC. The transmission of a PD shown in the figure blow is the comparison between the test results by using the PTS and test results by using a commercialized PNA from Keysight.
