A linear optical link using radiation hard VCSELs

A four-channel linear optical link has been developed to enable analogue data transmission in LHC experiments for the analogue front- end chip SCT128A. Signals from a prototype ATLAS SCT module, consisting of 12 cm long silicon strip detectors, connected to six 128 channel SCTA chips, have been tran...

Sumario:A four-channel linear optical link has been developed to enable analogue data transmission in LHC experiments for the analogue front- end chip SCT128A. Signals from a prototype ATLAS SCT module, consisting of 12 cm long silicon strip detectors, connected to six 128 channel SCTA chips, have been transmitted at 40 MHz using the Mitel 4D469 VCSEL and matching PIN diode at a wavelength of 850 nm. Results are presented showing static and dynamic linearity, frequency response and noise. The overall performance of the complete chain is shown for /sup 241/Am spectra. (4 refs).
