Method for measuring the speed parameters of photodetectors
https://doi.org/10.32446/0368-1025it.2020-8-36-42
Abstract
The article discusses the difficulties that arise when measuring the speed parameters of modern broadband photodetector devices by a method based on the measurement results of the rise time of the transition characteristic are considered. As a solution of the described problems a method is proposed for quantitatively evaluating of speed parameters using the results of determining the impulse response of the studied photodetector. The source of the test signals is a pulsed fiber laser operating in the self-mode locking mode and generating ultrashort (about 3 ps) optical pulses. The article describes in detail the method itself, the measuring setup that allows it to be implemented, and presents some results of experimental testing of the method.
