US Patent Issued to CLEMSON UNIVERSITY RESEARCH FOUNDATION on Feb. 24 for "High-power single-mode triple-ridge waveguide semiconductor laser" (South Carolina Inventors)

ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,562,550, issued on Feb. 24, was assigned to CLEMSON UNIVERSITY RESEARCH FOUNDATION (Clemson, S.C.).

"High-power single-mode triple-ridge waveguide semiconductor laser" was invented by Lin Zhu (Clemson, S.C.), Xiaolei Zhao (Clemson, S.C.), Yeyu Zhu (Clemson, S.C.) and Siwei Zeng (Clemson, S.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "To achieve high-power single transverse mode laser, we here propose a supersymmetry (SUSY)-based triple-ridge waveguide semiconductor laser structure, which is composed of an electrically pumped main broad-ridge waveguide located in the middle and a pair of lossy auxiliary partner waveguides. The auxiliary partner wave...
