Robust Fiber Optic Communication System for Harsh Aerospace Environments

Abstract:

In Phase I Photonics Research Incorporated proposes to design and
analyze a next generation (1 - 16,000 Mb/s) fiber optic data
transport system for spacecraft applications. In Phase II we will
construct the prototype system.

We will build on our expertise in telecommunication and computer
interconnects, guided-wave optics, and multi-wavelength
vertical-cavity surface emitting laser arrays. In Phase I we will
examine candidate architectures where a mix of data multiplexing
techniques (wavelength, space, and time) and a mix of innovative
optoelectronic components, multi-wavelength vertical-cavity
surface-emitting lasers and intelligent adaptive receivers are
employed to meet the specifications and requirements of aerospace
systems.

This communication link would be designed, through the choice of
components and architecture, to be robust with respect to component
failure, radiation and electromagnetic interference (EMI), large
temperature fluctuations, mechanical vibration and stress, and wide
manufacturing variations and operating conditions. The intent is
to better exploit the emerging strengths of guided-wave
optoelectronics, beyond simple transmission systems, while also
taking advantage of the strengths of conventional electronics.

The designed systems are intended to have large commercial product
potential and thus are inherently dual purpose. Implementation of
the proposed systems would provide the framework for several
fiber-optic network commercial products in local and wide area
networks. The estimated annual market size for short haul local and
wide area networks is in excess of $2.5B corresponding to 5,000
jobs within 5-7 years.
