Paper Abstract

A novel approach for the generation of optical minimum shift keying (MSK) signals is presented. The transmitter is based on merely one phase modulator (PM), which is driven by a phase controller. The receiver uses direct detection based on the Mach-Zehnder delay interferometer (MZI) and optical balanced receiver. In this paper, firstly the detailed principle on optical MSK generation and detection is derived and analyzed. Then, 40Gb/s optical MSK signal based on this scheme is successfully generated and transmitted over several fiber links (SMF+DCF) with only the first order dispersion compensation. Finally, the performance of the MSK based on PM is compared with that of the MSK based on other two known schemes, in terms of waveform, phase and spectrum. Simulation results show that not only this approach has a simpler architecture for the optical MSK transmitter, and but also the optical MSK generated has better performance.
