Abstract

We have proposed a silicon micro-ring based WDM modulator, which can simultaneously transmit data in BPSK, QPSK, and 16QAM modulation formats over different WDM channels. Here, we have considered two cases of a three channel WDM system, one with 50GHz channel spacing and another with 100GHz channel spacing. We have shown using numerical simulations the efficacy of simultaneous generation of 10Gbps BPSK, 20Gbaud QPSK, and 20Gbaud 16QAM over three WDM channels. We have analyzed the eye diagrams and signal constellations of different modulation formats both at back-to-back condition and after transmission over few tens of kilometers of standard single mode fiber.
