Abstract
A vertical optical switch consisting of an electro-optic polymer is described. Two-layer stacked slab waveguides were fabricated with para-nitroaniline-bonded epoxy polymer as the core layer and polyvinylalcohol as the cladding layer. After poling treatment, a He-Ne laser beam was coupled to the waveguides, and guided-wave switching was observed between the two waveguide layers with application of voltage to the electrodes.Keywords
