Title: Igor Krestnikov: Innovator in Photonic Technologies
Introduction
Igor Krestnikov is a prominent inventor based in Dortmund, Germany. He has made significant contributions to the field of photonic technologies, holding a total of 9 patents. His work focuses on advanced laser systems and integrated photonic circuits, showcasing his expertise and innovative spirit.
Latest Patents
One of Krestnikov's latest patents is for a "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 design features a lateral waveguide formed by selective oxidation of the aluminum-rich layer, along with a surface corrugated grating positioned above the waveguide. The structure is engineered to minimize optical losses by avoiding metallization above the waveguide, instead offsetting the metal contacts to ensure effective current distribution.
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 designs offer a straightforward fabrication process that requires only a single etching step, combined with well-controlled selective oxidation, enhancing manufacturability and reliability.
