Abstract:
1. A method for fabricating a coaxial structure having an inner electrical conductor surrounded by an optically conductive dielectric, comprising: creating an optical trench in a first electrical conductor; making a first deposit of an optical material into the optical trench to cover an inner surface of the trench; removing a portion of the first deposit of the optical material from the optical trench to form an embedded trench in the first deposit of the optical material; building up electrically conductive material from within the embedded trench to create the inner electrical conductor; making a second deposit of the optical material around an exposed portion of the inner electrical conductor to create an optical channel encapsulating the inner electrical conductor; and depositing electrically conductive material over a top surface of the optical channel and over a top surface of the first electrical conductor to create the coaxial structure.
