Abstract

Photopolymerizable organopolysiloxanes such as, for example, those listed in U.S. Patent 3,782,940 are selectively ex~ posed to actinic radiation, typically ultraviolet radiation, to cross-~link the material in the shape of the desired integrated component. Non~hardened portions of the material are removed leaving shaped, hardened material residing on a substrate,

Photopolymerizable organopolysiloxanes such as, for example,
those listed in U.S. Patent 3,782,940 are selectively ex~
posed to actinic radiation, typically ultraviolet radiation,
to cross-~link the material in the shape of the desired
integrated component. Non~hardened portions of the material
are removed leaving shaped, hardened material residing on a
substrate,

The hardened material, depending upon the shape imparted, is
used for integrated optics applications, For example, the
shape and accompanying function can be that of a planar
ridge waveguide, grating coupler, etc. Elastomeric silicone
polymers having photoactive groups such as amines can be
cross~-1inked by exposure to ultraviolet radiation,
