Optical switching system

摘要: An optical switching device switches signals completely within media, from an arbitrary number of N input fibers to a set M output fibers. The invention uses thermally-activated bimorph switch redirect radiation emitted by laser light source, or the end fiber, another fiber. modulated fiber optic bundle is collimated into parallel beams and projected in free space across tops array microcantilever switches. When selected, particular activated, thereby causing first element pop up, intercept reflect at angle approximately 90° original path direction. This reflected intercepted essentially identical element, located above below that directs plane beam plane, but right angles directed second collimating optics. then coupled selected
