▎ 摘　　要

NOVELTY - A deep-UV optical circuit comprises laser emitting light wavelengths ( lambda ) below 250 nm; graphene optical cable (16) containing optic core formed of vacuum with an index of refraction of 1 and cladding layer formed of graphene cylinder that is sealed at both ends to maintain the vacuum within graphene cylinder regardless of atmosphere external to graphene optical cable, where graphene cylinder consists of a contiguous lattice of covalently-bonded carbon atoms surrounding the optic core; and optical detector circuit configured to detect light. USE - A deep-UV optical circuit. ADVANTAGE - Replacing metal interconnect with optical interconnect provides improved power, latency, and bandwidth performance to match the enhanced scaling of transistors. The use of deep-UV signals across optical interconnect minimizes the diameter of the cores of graphene optical cables. In addition, the use of graphene as cladding for graphene optical cables reduces the thickness of the cladding layer to that of a monolayer of graphene, a bi-layer of graphene, or multilayer graphene. Minimizing the overall thickness of graphene optical cables through these features makes graphene optical cables compatible with the engineering drive to minimize the size of electrical components for microchips for performance improvements. DETAILED DESCRIPTION - A deep-UV optical circuit comprises laser emitting light wavelengths ( lambda ) below 250 nm; graphene optical cable (16) containing optic core formed of vacuum with an index of refraction of 1 and cladding layer formed of graphene cylinder that is sealed at both ends to maintain the vacuum within graphene cylinder regardless of atmosphere external to graphene optical cable, where graphene cylinder consists of a contiguous lattice of covalently-bonded carbon atoms surrounding the optic core; and optical detector circuit configured to detect light, where graphene optical cable optically couples the laser to the optical detector circuit, where optical cable transmits light wavelengths ( lambda ) below 250 nm as graphene has an index of refraction of less than or equal to 1 for light wavelengths ( lambda ) below 250 nm.
