His work primarily focuses on semiconductor optical amplifiers and optical waveguides, showcasing his expertise in enhancing optical signal processing.

Latest Patents

One of his latest patents is a semiconductor optical amplifier with a reduced noise figure. This invention is designed to amplify an optical signal effectively. The amplifier includes an input for receiving the optical signal and an output for delivering an amplified version of that signal. It features a semiconductor active medium that defines an amplification path, allowing the optical signal to be amplified as it travels along this path. Additionally, a control means is incorporated to selectively manage the amplified spontaneous emission (ASE) of the amplifier, working in conjunction with the active medium to vary carrier density along the amplification path.

Another significant patent is related to an optical waveguide and a method for providing it. This invention involves a laser diode that has an optical path defined in an active layer, which is sandwiched between a substrate layer and a top layer. The design includes a ridge formed in the top layer, which outputs laser light of a single predetermined wavelength. Refractive index altering grooves are strategically placed in the top layer to modify the refractive index of the active layer along the optical path. This setup facilitates the creation of standing waves or harmonics of the single predetermined wavelength, enhancing the efficiency of the optical system.
