Advances in III-V based Photonic Crystals for integrated optical processing

摘要

Compactness, massive integration of multiple functions on a single chip and power consumption are crucial for transmission of large aggregated bit rates at short distance. Efficient implementation of data processing at the optical level are very attractive. Here we present a technology for implementing ultra-fast switching with record-low energy-recovery time product. We developed high-quality photonic crystal micro-resonators based on III-V semiconductors. The very short carrier lifetime of nano-pattened Gallium Arsenide enabled us to achieve 6 ps recovery time, thus enabling operations beyond the 100Gb/s rate. For broadband operation, highly nonlinear waveguides with low insertion loss have been demonstrated.
