Latest Patents
One of 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, which is essential for achieving 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 allow current to spread in the cap layer before vertical injection into the core layer.
Another notable patent is for "Adiabatic mode-profile conversion by selective oxidation for photonic integrated circuit." This invention provides 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 advantage of these designs is their simple fabrication procedure, which requires only a single etching step combined with well-controlled selective oxidation. This results in improved manufacturability and reliability.
