Abstract

We report the first switching network compatible with multi-mode fibers. A 1-to-many cascaded reconfigurable interconnection was built. A thin glass substrate was used as the guiding medium which provides not only higher coupling efficiency from multi-mode fiber to waveguide but also better tolerance of phase matching conditions. Involvement of a total internal reflection (TIR) hologram and multi-mode waveguide eliminates interface problems between fibers and waveguides. The DCG polymer graft has proven to be reliable from -180°C to +200°C. Survivability of such an electro-optic system in harsh enviroments is further ensured. LiNbO 3 was chosen as the E-O material because of its stability at high temperatures (phase transition temperature >1000°C) and maturity of E-O device technology. Further theoretical calculation was conducted to provide the optimal interaction length and device capacitance.
