The S and P states of polarization of the mixed signal are analyzed with a pair of balanced detectors. Our PDR is housed in a compact, hermetically sealed, package with direct electrical connections to its four photodiodes.

A sample and reference signals are first split by a non-polarizing beam-splitter, followed by polarization state splitting by a polarizing beam-splitter. The resulting four channels (S+, S-, P+ and P-) allow polarization diverse detection with common mode rejection.

The G&H PDR family are available as discrete parts, or can be supplied attached to a Balanced Detector PCB. This board features noise filtering for maximum image quality and convenient interconnects to facilitate customer integration or evaluation.
