Nonparaxial analysis of the far-field radiation patterns of double-heterostructure lasers.

Previous analytical approximations for the far-field radiation patterns of a double-heterostructure laser have been restricted by TE-mode propagation in slab waveguides. A model that is applicable to both TE- and TM-mode propagation either in a slab waveguide or in a multiple-quantum-well structure is developed. Results of computations agree with the measured irradiance profiles of visible diode lasers of wavelengths from 635 to 670 nm. A process for deriving far-field expressions in terms of the diode-laser parameters listed in data books is suggested. Astigmatic aberration present in the wave front is determined, and the final result is expressed in a form convenient for diffraction analysis of truncated focused (or collimated) diode-laser beams.
