Achieving high reliability in silicon photonics optical transceivers for harsh environments over 100°C in excess of 10 year operation

In this paper we report on the design and performance of a silicon photonics micro-transceiver, which is designed to operate in harsh environments including high temperature environments above 105°C and space environments. In addition, we demonstrated that the micro-transceiver modules have been applied to immersion cooling, which must be considered another harsh environmental condition due to its novelty for optical active components. The four-channel “IOCore®” micro-transceiver incorporates a 1310 nm quantum dot laser system and operates at a symbol rate of 32 GBaud and higher. The 5 x 5 mm micro-transceiver chip benefits from a multimode coupling interface for low-cost assembly and robust connectivity at high temperatures.
