Abstract: An optical sampling method and apparatus are provided for modulating an optical signal using a first electroabsorption modulator (EAM) driven by a sinusoidal RF voltage signal to provide substantially jitter free temporal gating of the optical signal. The gated optical signal from the first EAM is routed through a second EAM to provide an optical output signal having a reduced repetition rate. The second EAM is driven using an electrical pulse train having a repetition rate that is a subharmonic of the frequency of the sinusoidal RF voltage signal driving the first EAM.

Abstract: A method and apparatus for polarization-independent RF spectrum analysis of an optical source, the apparatus including a coupler for coupling the light from an optical source under test with light from a continuous-wave (CW) laser. A nonlinear apparatus is coupled to the coupler for modulating the electric field of the light from the CW laser using the temporal intensity of the light from the source under test to generate a modulated signal. The nonlinear apparatus is adapted to mitigate or compensate for any phase difference between polarization components of signals propagated through the nonlinear apparatus. A polarizer is coupled to the nonlinear apparatus for generating a linearly polarized signal from the modulated signal. An optical spectrum analyzer is coupled to the polarizer for measuring the optical spectrum of the linearly polarized signal to determine an RF spectrum of the optical source under test.
