Abstract

Characterization of high-speed photodetectors by optical heterodyne and pulse response techniques is reported, and the results are compared. Scalar deconvolution was used to obtain photodetector response from the pulse response measurements with effects of the measurement apparatus removed. Linearity of the detector response is verified, validating comparison in the frequency domain using a Fourier transform of the pulse response data. The comparison is limited to the magnitude of the transfer function in the frequency domain, since the optical heterodyne technique does not give phase information. Both sets of results are corrected for the effects of their respective measurement systems. After these corrections, close agreement between results obtained by using the two techniques was found
