Abstract

High temperature operation characteristics and reliability of an ultra-small silicon photonics transceiver equipped with a quantum dot laser up to an ambient temperature of 105°C are reported. An ultra-small silicon photonics transceiver of 5 by 5 mm size, called IOCore, is integrated with an optical transceiver of 32Gbps (PCIeGen5.0) by 4 lanes. The combination of Fabry-Perot quantum dot laser and Mz modulator provides good transmit/receive characteristics at 32Gbps * 4 lanes at an ambient temperature of 105 degreesC. Reliability tests showed that the quantum dot laser was estimated to have a very high lifetime of 5.6fit when used at 105 degreesC. at 10 degreesC. IOCore can be applied to onboard optics for devices that are difficult to replace in case of failure, or to outdoor optical modules that require I-Temp. Some examples of module development are shown.
