Radiation hardness and lifetime of VCSELs and PIN photodiodes for use in the ATLAS SCT

Abstract:

This paper reports the radiation hardness of optical components to be used in the binary readout of one of the next generation of detectors in high energy physics. The optical components will have to sustain a total ionising dose of 500 kGy and a 1 MeV equivalent neutron fluence of 10(15)n cm(-2). Emitters of VCSEL type have been chosen and have shown a shift of 1 mA in the laser threshold current after irradiation, but are still suitable for our purpose. The epitaxial Si PIN photodiode recei...
