Abstract

An integrated optical device comprising at least one optical waveguide (2, 3) formed on a substrate, the waveguide (2, 3) being of elongate form with an optical axis extending along its length, at least one doped region (1) being provided in the substrate adjacent at least one side of the waveguide (2, 3), an edge of the doped region (1) adjacent the waveguide (2, 3) having one or more projections (1E, 1F) shaped to intercept stray light travelling substantially parallel to the waveguide (2, 3) in a region (4) of the optical substrate between the waveguide (2, 3) and the remainder of the doped region (1) and to absorb said light and/or deflect said light away from the waveguide (2, 3).
