Abstract
A novel measurement system based on an integrated-optic modulator has been used to determine the frequency response of a high-speed GaInAs photodiode. A nominally 8 GHz bandwidth modulator provided a 3 mu W levelled, continuously tunable, modulated optical signal to greater than 21 GHz. The measured detector 3 dB bandwidth was 19.2+or-0.8 GHz.
