Abstract
An optical switch which uses internal reflection at a junction formed by two waveguides is discussed. The waveguides may be formed from various materials such as polymers and other combinations of monomers. Substantially total internal reflection may be produced at the junction between the two waveguides in response to heating from a thin film electrode.
