Latest Patents

One of his latest patents is the "Compound cavity reflection modulation laser system." This invention relates to a compound cavity optical reflection modulation laser system that provides frequency modulation of laser light. It utilizes phase-induced effective reflection modulation of the laser rear facet. The system integrates a single-mode gain-coupled DFB laser with a passive waveguide section, forming a compound cavity modulation system. The waveguide features a multiple quantum well region that is reverse biased to utilize the quantum Stark effect for voltage-controlled refractive index modulation. This setup allows for phase modulation of the laser light, which is then fed back to the laser to interfere with the light generated within the laser, resulting in the output light generated from the compound cavity.

Another significant patent is the "Method and device for encoding data into high-speed optical train." This device includes N data encoding branches, each equipped with a dual-mode laser that generates at the beat frequency f, along with an external modulator. Each dual-mode laser consists of a laser structure with two sections formed on the same substrate, operating simultaneously at different longitudinal modes. The sections have a common active medium and shared optical path, allowing for mutual light injection. The signals from the branches are processed through a variable delay line, introducing phase shifts and compressing them in the optical compressor. This results in the formation of N short pulse optical trains, which are combined to create one combined optical pulse train of frequency Nf, achieving high-speed data encoding.
