Abstract :
A semiconductor double microring Mach-Zehnder (DM-MZ) modulator is proposed. Its operation principle and DC modulation characteristics are theoretically discussed. The DM-MZ enables a push-pull operation and the driving voltage can be significantly reduced compared to a conventional MZ modulator due to the phase-shift enhancement effect in a microring resonator.
