A 10-Gb/s Silicon Microring Resonator-Based BPSK Link

Abstract

We design and demonstrate for the first time an endto-end binary phase-shift keying (BPSK) link based on silicon microring resonators, with an operational bit-rate at 10 Gb/s. The obtained bit-error-rate is below the forward error correction limit, validating the practical application of the demonstrated technique. Performance comparisons to conventional BPSK modulation and demodulation techniques are also made. The microring-based BPSK link promises a compact, energy efficient, and low-cost interconnect solution for high-capacity transceivers.

“…On the other hand, phase-based modulation formats such as non-return-to-zero (NRZ) differential phase shift keying (DPSK) exhibit channels' constant amplitude envelop mitigating the effect of pattern dependent nonlinear effects. These advantages have accrued research interest with recent work on SOI platform proposing approaches for phase modulation [3] and demodulation [4]. At the receiving end, Manuscript a robust and compact SOI-DPSK demodulator is required to convert the phase modulated signal to intensity modulated signal for efficient photodetection.…”

A Compact Silicon Photonic DQPSK Receiver Based on Microring Filters

“…A single micro-ring can be used for the demodulation of DPSK signals [9] and demodulation up to 40 Gb/s has been experimentally demonstrated in [10] using a silicon micro-ring together with an external photodetector. A single micro-ring has been also previously employed for the demodulation of just one component of a DQPSK signals in [11].…”
