Latest Patents

One of his latest patents is the "Wavelength sliced self-seeded pulsed laser." This invention is designed to produce pulses of light with predetermined spectral shapes. It comprises a waveguide, an optical pump source, a gain medium to generate seed radiation, and a modulator along with an array of Bragg gratings to modify the properties of the seed radiation. The seed radiation, once generated by the gain medium, propagates through the waveguide, where it is pulsed by the modulator. The resulting pulses are selectively reflected by the Bragg gratings, which separate different spectral components of the reflected beam. This reflected beam then travels back to the modulator, which is timed to allow only the desired spectral components to pass through. This self-seeding mechanism enables spectrum and wavelength selection from pulse to pulse.

Another significant patent is the "Optical device employing edge-coupled waveguide geometry." This optical device is designed for modulating or interacting with radiation that is guided and propagating along the longitudinal axis of an optical waveguide, such as an optical fiber. It features a different directional geometry compared to conventional devices, including a nonlinear, electro-optic medium formed between two spatially disposed electrodes. The medium/electrode configuration is aligned along the waveguide's longitudinal axis and extends radially from the optical waveguide core, allowing for evanescent coupling with the radiation field. By applying an electric field to the electrodes, the refractive index of the electro-optic medium can be varied, inducing a lossy condition on the propagating radiation. This modulation of the electric field results in intensity modulation of the radiation.
