Manufacturers : Optoelectronics : Optical switches
Optical signals are commonly transmitted in optical fibers, which provide efficient light channels through which optical signals can pass. Optical switch devices are essential to wavelength division multiplexing (WDM) indispensable in an optical network serving as a base of, e.g., the Internet communication network. In optical fiber systems, various mechanisms have been previously developed for switching optical signals between fiber cables. Generally, an optical switch functions to change a path of an optical signal transmitted through an optical fiber in a WDM optical communications network. The primary optical switching technologies used today are micro electromechanical systems (MEMS), liquid crystals, and bubbles. There are two types of optical switches which include a waveguide type optical switch using a quartz optical waveguide or a lithium niobate crystal optical waveguide, and a mechanical optical switch that mechanically moves an optical fiber or a prism.
