Recent Radiation Effects Activities at JPL: Coping with COTS

The rediation effects and testing programs in place at the Jet Propulsion Laboratory support the insertion of traditional, advanced, and emerging microelectronic and photonic technologies in NASA systems through research and testing that enhances the radiation hardness assurance (RHA) of these technologies. With the decreasing availability of radiation hardened electronics and the new NASA paradigm of faster, more aggressive and less expensive space missions, there has been an increasing emphasis on using high performance commercial microelectronic parts and circuits in NASA spacecraft.

Radiation Effects in Photonic Modulator Structures

%T Radiation Effects in Photonic Modulator Structures%A Charles Barnes%A Roger Greenwell%J SPIE, Photonics for Space Environments%C Orlando, Florida, U.S.A.%D April 18-20, 1995%K Radiation%K Photonic Modulator Structures%U http://techreports.jpl.nasa.gov/1995/95-1057.pdfA review is given of the effects of radiation on various photonic modulator materials and devices including polymer-based structures, insulator-based devices, semiconductor-based devices and spatial light modulators. We conclude by providing recommendations for further work in the area of radiation effects in photonic modulators.!
