  • A METHOD OF PREPARING A PLANAR OPTICAL WAVEGUIDE ASSEMBLY
    Publication number: 20200278611
    Abstract: This invention relates to a method of preparing a planar optical waveguide assembly comprising the steps of: (i) applying a curable silicone composition to a surface of a substrate to form a film; (ii) exposing the product of step (i) to ultraviolet light to form a lower clad layer; (iii) applying a photo sensitive composition on top of the lower clad layer to form a core layer on top of the lower clad layer, wherein the photo sensitive composition comprises: (A) a siloxane resin composition comprising 0 to 95 mole present of R1SiO3/2 siloxane units, 0 to 95 mole percent of R2SiO3/2 siloxane units, and 1 to 99.
