Abstract

We report the first electro-optic switching device compatible with multimode 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 TIR hologram and multi-mode waveguide eliminates interface problems between fibers and waveguides. The DCG holographic material has proven to be reliable from -180°C to +200°C. Survivability of such an electro-optic system in harsh environments is further ensured. LiNbO3 was chosen as the E-O material becuase 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 cpacitance.
