Abstract :
In this paper, we describe the development of a diffuse infrared optical backplane technology for small satellites. After an overview of the system architecture and previous work, we discuss the design and implementation of a radiation tolerant interface ASIC. This ASIC, which is fabricated in a silicon-on-sapphire process, contains test circuits for the interface between the photonic components (VCSEL and PiN photodiode) and the transceiver´s digital logic. In addition, we describe further work towards the improvement of our system´s range and the creation of a fully integrated digital node
