Abstract

It has been demonstrated that power (>95%) can be switched between an optical fibre, side polished close to the core, and a high index multimode waveguide overlay. Using lithium niobate sandwiched between optically transparent indium-tin-oxide electrodes in the role of the overlay, electro-optic switching has been observed. By applying a second polished fibre block to the top surface of the overlay, power may be switched between two fibres. This paper addresses such issues as insertion loss, switching voltage and on off ratios in these devices.
