METHOD FOR RECOVERING CLOCK INFORMATION FROM A RECEIVED OPTICAL SIGNAL

摘要

The invention relates to a method (100) for recovering clock information from a received optical signal, the received optical signal having a first (x) and a second (y) principal state of polarization. The method comprises modifying (101) the first and the second principal state of polarization according to an optimization criterion and detecting (103) the clock information based on the modified first and second principal states of polarization.
