Low power consumption operation of light sources for inter-chip optical interconnects

In this work, we present a multi-channel configuration for the low power consumption operation of light sources on a silicon substrate in a photonics-electronics convergence system. We simulated the power consumed by the entire system with a focus on the characteristics of a laser diode used as a light source and the total loss of the system. Simulation results showed that lower power consumption per channel can be achieved with a single-LD multi-channel branching configuration. We found that using a hybrid integrated light source on a Si substrate with this branching configuration is suitable for photonics-electronics convergence systems.
