Generation and detection of 80-Gbit/s return-to-zero differential phase-shift keying signals
15 December 2003
Nonlinear polarization rotation between a pump and a probe signal in a highly nonlinear fiber is used as a modulation process to generate 80-Gbit/s return-to-zero differential phase-shift keying signals. Its performance is analyzed and compared with a conventional on-off keying modulated signal. (C) 2003 Optical Society of America.
