We propose to use silicon photonics technology to build
radiation-hard fiber-optic links for high-bandwidth readout of tracking
detectors. The CMOS integrated silicon photonics was developed by Luxtera
and commercialized by Molex. The commercial off-the-shelf (COTS) fiber-optic
links feature moderate radiation tolerance insufficient for trackers. A
transceiver contains four RX and four TX channels operating at 10 Gbps each.
The next generation will likely operate at 25 Gbps per channel. The approach
uses a standard CMOS process and single-mode fibers, providing low power
consumption and good scalability and reliability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
