High-speed resonantly enhanced silicon photonics modulator with a large operating temperature range

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 compared 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 temperature range spanning 55°C.
