Introduction
Siamak Forouhar is a prominent inventor based in Pasadena, CA (US). He has made significant contributions to the field of semiconductor lasers, holding a total of 7 patents. His work focuses on advancing the technology behind quantum cascade lasers and interband cascade lasers.
Latest Patents
One of his latest patents is titled "Index-coupled distributed-feedback semiconductor quantum cascade lasers fabricated without epitaxial regrowth." This innovation provides methods for fabricating quantum cascade lasers that incorporate a distributed feedback (DFB) grating without relying on epitaxial regrowth processes. The DFB gratings can be formed as sidewall gratings along the lateral length of the quantum cascade active region or atop the active region, with the top DFB grating being planarized using a polymeric material. Another notable patent is for "Single-mode, distributed feedback interband cascade lasers." This invention describes single-mode interband cascade lasers (ICLs) that utilize distributed-feedback gratings, such as lateral Bragg gratings, and outlines methods for their fabrication. The ICLs feature distributed-feedback gratings positioned above the laser active region and adjacent to the ridge waveguide.
