Technology development in photonics is rapidly progressing. The concept of a Unified Network will provide re-configurable network access to platform sensors, Vehicle Management Systems, Stores and avionics. The re-configurable taps into the network will accommodate present interface standards and provide scaleability for the insertion of future interfaces.Significant to this development is the design and test of the Optical Backplane Interconnect System (OBIS) funded by Naval Air Systems Command (NAVAIR) and developed by Lockheed Martin Tactical Defense Systems -Eagan (LMTDSEagan). OBIS results in the merging of the electrical backplane and the optical backplane, with interconnect fabric and card edge connectors fmally providing adequate electrical and optical card access. Presently OBIS will support 1 .2 Gb/s per fiber over multiples of 12 fibers per ribbon cable.
This paper describes a solid state high speed fiber-optic switch based on dynamically alterable magnetic stripe domains that occur naturally in epitaxial films of rare-earth iron garnet. The array of stripe domains acts collectively as a Faraday effect phase diffraction grating that deflects visible and infrared radiation. Electrically derived magnetic fields in the plane of the film steer incident light from an input fiber to one of several output fibers. Reciprocity and wavelength sensitivity can be exploited for systems applications. Both theoretical and experimental results are presented.
First-order diffraction efficiency of 50% into a single beam was obtained from a weak symmetric square metal diffraction grating operated in an étalon at the 632.8-nm He-Ne laser wavelength. Without the étalon the diffraction efficiency was just 2.7% in each of the two first-order beams. First-order diffraction efficiency gain as well as blazing and apodizing of the grating occur because of the resonant paraxial angular spectrum of the étalon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
