Abstract
A process for forming glass planar waveguide structure includes producing or obtaining a fusion drawn glass laminate (10) comprising a core glass layer (10) and a first clad glass layer (14) and a second clad glass layer (16) then removing or thinning portions of at least the second glass clad layer (16) leaving remaining or thicker portions of the second glass clad layer (16), the remaining or thicker portions corresponding to a planar waveguide pattern and resulting in a glass planar waveguide structure.
