Abstract
A hybrid laser for generating radiation includes an optical passive material and an optical active material. The laser includes a first optical waveguide and optical laser components with reflectors in the optical passive material. The first optical waveguide is adapted for coupling out radiation from the hybrid laser. The laser also includes a second optical waveguide defined in the optical active material. The optical laser components include reflectors defining a cavity and furthermore are adapted for providing laser cavity confinement in the first optical waveguide and the second optical waveguide. The second optical waveguide thereby is positioned at least partly over the first optical waveguide so that an evanescent coupling interface is defined between the second optical waveguide and the first optical waveguide and the evanescent coupling interface is positioned within the laser cavity.
