Abstract :
LEDs and photodiodes (PDs) suitable for OWLS were irradiated with 52 MeV protons and up to 2.8ldr1012 p/cm2 (in 5 steps). Electrical and optoelectronics parameters have been characterized during the test (characteristic I-V curve, dark current, PD responsivity and LED optical power) results about degradation and are reported. Also, the differences in degradation rate for several biasing conditions during irradiation have been studied.
