A Scalable Low-Power Optical Chip: Realization and Static Loss Analysis

Optical interconnects outperforms the traditional electrical interconnects with lower power consumption, higher bandwidth density and scalability. We propose a scalable optical interconnect for on- chip core-to-memory communication. The key part of the optical interconnect is scalable optical switching blocks, which use less microring resonators with different wavelengths to provide higher parallelism for the memory access communication. We demonstrate the 4-port switching block with six microring resonators. The experimental results show the average insertion loss of 4-port optical switching block is 6.956 dB.
