Abstract

Interposers for inter-chip interconnects should perform stably under high-temperature conditions and rapid temperature change due to the heat generated by mounted large-scale integration (LSI) chips. Athermal silicon optical interposers integrated with quantum dot lasers and other temperature-insensitive components on a single silicon substrate are demonstrated, and error-free data links at 12.5 Gbit/s operating from 25 to 125°C are achieved without any bias adjustment. Since maximum junction temperatures in most LSIs have been below 125°C now and will be in the future, the interposers are tolerant of heat generated by LSIs, and are suitable for inter-chip interconnects.
