Abstract
A process for forming an integrated optical device in a substrate, comprising the steps of: providing a substrate having a base index of refraction; providing a UV light beam; focusing the beam on a portion of the substrate in order to form a region of increased refraction; and scanning an elongated region of the glass substrate with the beam in order to define at least one elongated optical channel having an increased index of refraction relative to the base index of refraction, the elongated optical channel for guiding light transmitted there along. The process further includes: forming a plurality of elongated optical channels in the substrate, wherein a first optical channel is operative for transmitting light to the plurality of elongated optical channels such that the transmitted light is divided among the plurality of elongated optical channels, thereby forming an optical beamsplitter.
