Abstract
An optical switch is disclosed which includes hollow waveguide structures having cantilevered beam deflectors to couple light out of the waveguide plane. An array of such waveguides with deflector combinations may be fabricated on a substrate. By combining substrates, devices such as all-optical cross bar switches, image display and scanning devices may be created.
