Abstract :
We propose a simple method which allows for a direct measure of the frequency response of photodetectors up to very high frequencies and avoids some of the problems inherent in the standard time-domain or frequency-domain measurements. This method is based on the detection of the tunable beat frequency obtained by superimposing the EM fields of two monomode semiconductor lasers.
