Described herein are examples of improved semiconductor lasers having improved facet reliability for operation at high power and high current without significant change in device performance. The semiconductor laser may include a first semiconductor layer, an active layer, a second semiconductor layer sequentially adjacent to each other and arranged on a substrate, and a contact layer. In one example, the improved semiconductor laser may have a conductive contact less than the length of the semiconductor laser cavity and/or a dielectric layer arranged on at least one of the end portions of the contact layer.

Semiconductor laser having improved facet reliability

A laser structure may include a substrate, an active region arranged on the substrate, and a waveguide arranged on the active region. The waveguide may include a first surface and a second surface that join to form a first angle relative to the active region. A material may be deposited on the first surface and the second surface of the waveguide.
