ABSTRACT:
A laser cavity is provided by a reflecting spherical substrate with an array of emitters having a mode size. Each emitter has an axis aligned with a radius of the spherical substrate. A single mode waveguide is aligned with the array at an optical coupling distance less than the radius of the spherical substrate. A reflector substantially coincident with an end of the waveguide combines with the reflecting spherical substrate as a cavity.
