Latest Patents
Among his latest patents is the "Single-step-grown transversely coupled distributed feedback laser." This invention describes a transversely-coupled distributed feedback laser diode that can be processed without overgrowth. The laser is constructed from an epitaxial heterostructure that includes a core layer situated between two cladding layers, a cap layer, and at least one aluminum-rich layer. The lateral waveguide is created through selective oxidation of the aluminum-rich layer, and a surface corrugated grating is positioned above the waveguide. The design ensures that the core layer is in close proximity to the top of the laser structure, allowing for the necessary overlap between the light and the grating. To minimize optical losses, there is no metallization above the waveguide, with metal contacts offset to require current spreading in the cap layer before vertical injection into the core layer.
Another notable patent is the "Adiabatic mode-profile conversion by selective oxidation for photonic integrated circuit." This invention presents waveguide designs and fabrication methods that enable adiabatic waveguide eigen mode conversion. These methods can be applied to the monolithic vertical integration of active and passive elements in photonic integrated circuits (PICs). The designs and methods offer a straightforward fabrication process that involves only a single etching step, followed by well-controlled selective oxidation, enhancing manufacturability and reliability.
