Hybrid silicon quantum dot lasers (hsqdl) with reduced thermal resistance
Patent published on the 2025-07-03 in WO under Ref WO2025144532 by INTEL CORP [US] (Huang Duanni [us], Su Guan-lin [us], Mehta Karan [us], Yerkes Shane [us], Dehghannasiri Razi [us], Dobek Stanley [us], Cramer Marcus [us], Frish Harel [us], Rong Haisheng [us])
Abstract: Hybrid silicon quantum dot laser (HSQDL) structure including an optical waveguide of a first width, a mesa of a second width and a current channel of a third width that is smaller than the second width. In some examples, the third width is only slightly larger than the first width to narrowly confine electrical current directly over the optical waveguide while the third width is significantly larger than the first width to efficiently transport heat away from the optical gain medium. While the c[...]
Our summary: Hybrid silicon quantum dot lasers with reduced thermal resistance have a structure that includes an optical waveguide, mesa, and current channel of varying widths to confine electrical current and efficiently transport heat away from the optical gain medium. Implant processes may be used to increase electrical resistivity in certain regions.
