Abstract

IOCore^TM is a 5 mm × 5 mm silicon photonic micro transceiver with a multimode interface. IOCore features four lanes for transmitting and receiving, and 25 Gbps/lane and 32 Gbps/lane have been released. A Fabry-Perot quantum dot laser in the 1.3 micrometer band is applied as the light source. This facilitates low-cost assembly with a multimode coupling interface and robust connectivity at high temperatures. With the increasing power consumption of IT equipment, there is a need to respond to high temperature operation and excellent cooling capacity using immersion cooling technology. In recent years, it has been proposed to mount the transceiver on the system board or LSI package to achieve high throughput with low power consumption. These transceivers require high reliability because they are difficult to repair. This study summarizes and reports on the design and evaluation of IOCore, which has been partially published previously, including its high temperature operation (105 °C), suitability for immersion systems, and reliability.
