Abstract

We demonstrate a >1-Tb/s VCSEL-based on-board optical engine for high-density optical interconnects. The optical engine integrates 28-Gb/s × 24-channel transmitter and receiver into one package of 1-inch² footprint. Hence, the total data rate is as high as 1.34 Tb/s. The thermal simulation is performed when operating all 24 channels with the total power of 9.1 W with CDR and 6.0 W without CDR, assuming an actual air-cooling environment. The optical engine can perform within the operating case temperature range at an ambient temperature of 40 °C and exhibit a good signal quality in a parallel loop-back link.
