Abstract
In an integrated optical lightguide device including a light-transmitting core layer, an inclusion or buffer layer, and an active or cladding layer. The cladding layer is divided into segments. Groups of different segments exhibit different refractive indices, light intensity profiles or different degrees of sensitivity which have been effected by different methods. Thus, repeated adjustable or controllable transmission has resulted in an extremely sensitive waveguide system for a sensor, a modulator, or a spectrophotometer.
