Latest Patents

One of his latest patents is for a broadband light source using a rare earth doped glass waveguide. This innovative design utilizes an optically pumped waveguide to produce superfluorescent light. The waveguide is constructed within a glass substrate, allowing the pump light to enter from one end while the output is emitted from the opposite end. A grating positioned near the output end effectively separates the pump light from the emitted light.

Another significant patent is for an integrated optics chip and a method of connecting optical fiber to it. This invention addresses the challenges of polarization cross coupling in fiber optic rotation sensors. It eliminates the need for time-consuming and costly alignment of the optical fiber sensing coil and the optical waveguides. The chip features a substrate made of optically active material with slots for mounting optical fibers. The optical waveguide is designed to guide signals along a specific axis, minimizing light reflection at the end surface of the waveguide.
