Abstract:

We present a novel resonant Mach–Zehnder modulator whose arms are each loaded with five identical resonators. Size and power consumption are aggressively reduced com- pared to conventional modulators based on linear phase shifters. At the same time, a large optical bandwidth of 3.8 nm is maintained. We experimentally demonstrate open eye diagrams at 30 Gbps with a signal Q-factor remaining within a factor of 2 of its peak value in an operational temper- ature range spanning 55°C.
