Abstract: A vertical-cavity surface-emitting laser (VCSEL) includes first reflector having a first reflectivity; a second reflector having a second reflectivity, where the second reflectivity is less than the first reflectivity; a gain region between the first and second reflectors; and a substrate having a first surface and a second surface, where the first surface is coupled to the second reflector, and where the second surface is formed into a lens to act upon light emitted the VCSEL through the substrate. The VCSEL lases in a single transverse mode.

Abstract: Examples of the present disclosure include a tunable laser comprising an optical coupler to couple light between a first laser cavity and a second laser cavity. The first laser cavity may extending between the optical coupler and a first reflector and include a first gain section. The second laser cavity may extend between the optical coupler and a second reflector and including a second gain section. At least one of the first laser cavity and the second laser cavity is tunable.

Abstract: Examples of the present disclosure include a tunable laser comprising a waveguide including gain section. The waveguide overlies and is optically coupled to another waveguide. The another waveguide has a reflector at one end. A laser cavity is formed in the waveguides.
