A new method for determination of time-resolved frequency chirp in modulated light sources of optical communication systems is presented. A thin silicon wafer acting as a low-finesse etalon was used as an optical frequency discriminator. The method provides a polarization-insensitive way to easily characterize the frequency chirp with high time-resolution.
