Abstract
An interband self-mode-locked (SML) semiconductor laser utilizes an active waveguide structure that includes an active waveguide section and one or more passive waveguide sections that together enhances self-mode-locking. The SML laser operation is based on enhanced Kerr lens mode-locking by vertically optically combining the active section with one or more passive waveguide sections.
