Radiation sensitivity of light emitting diodes (LED), laser diodes (LD) and photodiodes (PD)

Commercially available diodes were irradiated at a flash X-ray source, a /sup 60/Co gamma ray source, and a 14-MeV neutron generator. During irradiation at the /sup 60/Co source, the light output of the LEDs and LDs was measured continuously. From time to time their emission spectrum was also observ...

Description
Summary:Commercially available diodes were irradiated at a flash X-ray source, a /sup 60/Co gamma ray source, and a 14-MeV neutron generator. During irradiation at the /sup 60/Co source, the light output of the LEDs and LDs was measured continuously. From time to time their emission spectrum was also observed. With the PDs the authors measured the preamplifier output during /sup 60/Co irradiation as well as dark current noise before and after irradiation. Determination of the sensitivity against neutrons was made offline. After pulsed irradiation of PDs the authors measured how long a certain type of preamplifier was overdriven by the induced photocurrent. LEDs and LDs showed a maximum decrease of output power of only 0.5 dB up to a total gamma dose of 10/sup 6/ Gy or neutron fluences of 4*10/sup 13/ cm/sup -2/ (1 MeV), respectively. Irradiations of PDs with /sup 60/Co gammas up to a total dose of 10/sup 6/ Gy as well as irradiations with neutrons up to fluences of
