Silicon photonics modulators are being investigated for use in optical links for High Energy Physics experiments. In order to withstand the harsh environment in experiments beyond the Large Hadron Collider at CERN, components will have to be resistant against extreme levels of radiation. We show that modulators, which lost their functionality after irradiation, can be fully recovered by...
Long-reach data transmission is an enabling technology for Accelerator Instrumentation at CERN. We present the development of next generation radiation-hard single-mode optical links. This new design aims to support the increasing data volume produced by the beam sensing electronics deployed along the accelerators. We present design of the new optical data link and its characterization in...
We report the design and irradiation results of a radiation-tolerant low-power 4x10 Gbps VCSEL Driver array IC in 65 nm CMOS. The driver IC consumes 130 mW at 4x10 Gbps and occupies 1.9 mm x 1.7 mm. The IC is capable of sustaining TID up to 300 Mrad and produces no errors after being irradiated with a total fluence of 2.8e15 20Mev neutrons over 36 hours. The IC is powered by 1.2 V for the...
We present an optical transmitter (MTx+) and transceiver (MTRx+) based on LC-TOSA/ROSA. MTx+ and MTRx+ use the dual-channel VCSEL driver ASIC LOCld65, developed in a 65-nm CMOS technology and tested up to 14 Gbps. For the moment MTRx+ uses a GBTIA-embedded ROSA. The electrical connector is the same as that in SFP+. Both MTx+ and MTRx+ receive multimode LC-connectorized fibers. The module is...
