Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
An integrated optical component comprising a monolithic glass body, at least one cavity molded into a surface of said glass body, and an optical circuit path formed in said surface by ion exchange, said path comprising the same constituents as said glass body and further including ions that increase the refractive index thereof to a value greater than that of said glass body, said path terminating at and being aligned with said cavity, whereby an optical device situated in said cavity is optically aligned with said circuit path.
Claim 2
Dependent Claim
88 words
An integrated optical component comprising a monolithic glass body, at least one cavity molded into a surface of said glass body, and an optical circuit path formed in said surface by ion exchange, said path comprising the same constituents as said glass body and further including ions that increase the refractive index thereof to a value greater than that of said glass body, said path terminating at and being aligned with said cavity, whereby an optical device situated in said cavity is optically aligned with said circuit path.
Claim 3
Dependent Claim
13 words
A component in accordance with claim 1 wherein said glass body comprises fluorine.
Claim 4
Dependent Claim
14 words
A component in accordance with claim 1 wherein said glass is a fluoroborosilicate glass.
Claim 5
Dependent Claim
13 words
A component in accordance with claim 1 wherein said cavity is a V-groove.
Claim 6
Dependent Claim
33 words
A component in accordance with claim 4 wherein said V-groove has an optical quality endface adjacent said circuit path, said endface being substantially perpendicular to the axis of said path at said endface.
Claim 7
Dependent Claim
24 words
A component in accordance with claim 1 wherein said body is formed of a glass having a softening point temperature less than 500° C.
Claim 8
Independent Claim
72 words
A method of making an integrated optical component comprising molding a glass monolithic body having at least one cavity in a surface thereof, and generating in said surface in alignment with said cavity by the ion exchange technique an optical circuit path, one end of which is in alignment with said cavity, whereby an optical device that is positioned in said cavity will be optically aligned with respect to said circuit path.
Claim 9
Independent Claim
72 words
A method of making an integrated optical component comprising molding a glass monolithic body having at least one cavity in a surface thereof, and generating in said surface in alignment with said cavity by the ion exchange technique an optical circuit path, one end of which is in alignment with said cavity, whereby an optical device that is positioned in said cavity will be optically aligned with respect to said circuit path.
