2×10 Gbit/s NONRETURN-TO-ZEROOOK TO 10 Gbaud QUASICONTINUOUS PHASE MODULATION ALL-OPTICAL CONVERSION USING CASCADED MACH-ZEHNDER INTERFEROMETERSEMICONDUCTOR OPTICAL AMPLIFIERS

摘要

An optical format conversion from nonreturn-to-zero (NRZ) to quasicontinuous phase modulation (Qu-CPM) using two Mach-Zehnder interferometer-semiconductor optical amplifiers in serial is presented, and its feasibility is demonstrated in a 2×10 Gb/s NRZ-OOK to one 10 Gbaud Qu-CPM conversion experiment.
