Non-blocking N×N thermo-capillary optical matrix switch using silica waveguide technology
Mitsuhiro Makihara · 2002
Space-division optical switches are essential for realising the optical cross-connects and protection switches needed in future fiber-optic communication networks. Optical switches fabricated by using silica waveguide technology work well with optical fibers in terms of connectivity and have excellent optical characteristics. They are also suitable for mass production. This paper describes a thermo-capillary optical matrix switch using silica-based waveguide. The switch has a simple structure as well as high transparency and is small and self-latching. It is applicable to a wide variety of fields where high-speed switching is not required.
