ABSTRACT:
A system and method for providing polarization-independent optical sampling utilizes a differential group delay (DGD) element to split a sampling pulse source (SPS) into orthogonal components by controlling the state of polarization of the SPS at the DGD element input. The orthogonally-polarized sampling pulse components then each interact with the input optical signal waveform in a polarization-dependent sampling gate, creating two samples for each original sampling pulse. The generated samples are converted into the electrical domain by a photodetector with an impulse response time longer than that associated with the DGD element, resulting in a single impulse response representing the combined energy of the two samples that is independent of the state of polarization of the input optical signal waveform.
