Beam propagation in an active planar waveguide with an angled bragg grating (α laser)

In the angled Bragg grating semiconductor laser (α laser), light does not propagate at a right angle with respect to the two-dimensional corrugated grating of the planar waveguide. A closed-form solution of the coupled-wave theory is used to describe the propagation of both the wave fields with diff...

Description
Summary:In the angled Bragg grating semiconductor laser (α laser), light does not propagate at a right angle with respect to the two-dimensional corrugated grating of the planar waveguide. A closed-form solution of the coupled-wave theory is used to describe the propagation of both the wave fields with different directions. A constant gain is included. Some properties of the main wave and of the secondary wave are described, which are of interest for the α laser. Additional losses occur during facet reflection of the secondary wave.
