Abstract :
The far-field pattern of a multimode surface-emitting AlGaAs distributed Bragg reflector laser was spectrally resolved with respect to emission angle. A simple analysis of the angular dependence of the far-field spectrum yields the waveguide effective index and the dispersion of the effective index.
