Abstract :
We propose and demonstrate a novel transmitter that enables versatile format generation with pulsewidth tunability. The transmitter is based on a single dual-parallel Mach-Zehnder modulator. By simply switching the driving and biasing conditions of the modulator, duobinary, return-to-zero alternate mark inversion and Manchester formats are obtained in a similar transmitter configuration. The back-to-back and transmission performances of the generated signals are investigated by experiments
