We propose the simple and efficient generation of a compact azimuthally polarized laser beam.Radial slits with annular distribution are patterned onto the output facet of a standard vertical-cavity surface emitting la...
Based on the transfer matrix method, we present a new one-dimensional steady-state model of vertical-cavity semiconductor optical amplifiers (VCSOAs), in which the longitudinal carrier concentration distribution in ...
