| Abstract(in English) | We propose clock extraction and optical time-division demultiplexing schemes based on signal processing in the optical frequency domain using phase modulation and spectral filtering. An optical phase comparator for clock extraction based on our scheme has high dynamic rage over 9dB and high sensitivity comparable to a conventional scheme using electrical mixers. Using our phase comparator, we construct a phase-locked loop for clock extraction from a 160-Gbit/s optical signal, where an additional timing jitter of an extracted clock RF is less than 10fs. In addition, our scheme is applicable to optical time-division demultiplexing from 160Gbit/s to 40Gbit/s, where the power penalties of all tributaries are less than 2dB. We show a 160-Gbit/s OTDM receiver with clock extraction and optical time-division demultiplexing functions based on signal processing in the optical frequency domain, and demonstrate good performance of our receiver for 160-Gbit/s optical sisnal. |
