Measuring the Frequency Response of Gigabit Chip Photodiodes



Paul D. Hale, Tracy S. Clement, Dylan F. Williams, E. Balta, N. D. Taneja


We describe a calibratin and measurement procedure for determining the intrinsic frequency response fo gigabit chip photodiodes embedded in simple test fixtures. The procedure is unique because we make the measurements in the time-domain using a calibrated oscilloscope and we then apply frequency domain mismatch corrections to remove the effects of the fixture, bias tee, and cables from the measurements. WE demonstrate the procedure on photodiodes with an active region of approximately 150 m diameter excited by short 800 nm optical pulses.
