For calculation of the amplitude and phase profile on the laser front mirror (or the
waveguide front), we make use by the wave equation solution, taking into account
that the complex permittivity ε(x, y) inside the resonator has the following form in
the transverse section:

The electrode is the strip contact, d 0 is the thickness of the active layer (junction), L is the laser
resonator length between mirrors, l 1 is the strip width, and l is the parameter of the layer width. The
