| 英文摘要 | A very large mode (VLM) slab-coupled optical waveguide laser (SCOWL) is provided that includes an upper waveguide region as part of the waveguide for guiding the laser mode. The upper waveguide region is positioned in the interior regions of the VLM SCOWL. A lower waveguide region also is part of the waveguide that guides the laser mode. The lower waveguide region is positioned in an area underneath the upper waveguide region. An active region is positioned between the upper waveguide region and the lower waveguide region. The active region is arranged so etching into the VLM SCOWL is permitted to define one or more ridge structures leaving the active region unetched. One or more mode control barrier layers are positioned between said upper waveguide region and said lower waveguide region. The one or more mode control barrier layers control the fundamental mode profile and prevent mode collapse of the laser mode. The mode control barrier layers also block carrier leakage from the active region. These layers are essential to obtaining VLM SCOWLs. |
