Abstract: A deep-UV optical circuit includes a laser emitting light wavelengths (λ) below 250 nm. The circuit also includes a graphene optical cable formed of an optic core formed of a gas or vacuum having an index of refraction ranging between 1.000 and 1.002 and a cladding layer formed of a graphene cylinder made of a contiguous lattice of covalently-bonded carbon atoms surrounding the optic core. The circuit also includes an optical detector circuit configured to detect the light. The graphene optical cable optically couples the laser to the optical detector circuit, where the optical cable transmits light wavelengths (λ) below 250 nm as graphene has an index of refraction less than 1 for light wavelengths (λ) below 250 nm.

Abstract: Holey fibers provide optical propagation. In various embodiments, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and higher modes of a signal, thereby allowing the non-fundamental modes to be substantially eliminated by leakage over a given length of fiber. Fine tuning of leakage losses can be performed by adjusting the hole dimension and/or spacing to yield a desired operation with a desired leakage loss of the fundamental mode. Resulting holey fibers have a large hole dimension and spacing, and thus a large core, when compared to traditional fibers and conventional fibers that propagate a single mode. Other loss mechanisms, such as bend loss and modal spacing can be utilized for selected modes of operation of holey fibers.

Abstract: The present invention is a device for sterilizing microorganisms on a liquid or solid substrate. The device includes a light source for producing a light and an optical device positioned proximate the light source. The optical device is configured to focus the light generated by the light source to provide a high intensity light output. The optical device also includes a dichroic reflector. The dichroic reflector is configured to pass thermal energy generated by the light source and reflect the light produced by the light source. The device also includes a power supply, where the power supply is coupled to the light source and the optical device.
