Abstract
Aspects described herein include an optical waveguide emitter that includes a first optical waveguide and a second optical waveguide that are evanescently coupled and collectively configured to selectively propagate only a first mode of a plurality of optical modes. Each of the first optical waveguide and the second optical waveguide extend through an input waveguide section, a turning waveguide section, and an output waveguide section. One or more of the input waveguide section, the turning waveguide section, and the output waveguide section includes an optically active region. The optical waveguide emitter further includes a refractive index-increasing feature in the turning waveguide section.
