Abstract :
We present novel surface emitting semiconductor laserdiodes based on the excitation and emission of surface modes. By coupling the laser mode to a surface mode we achieve surface emission from conventional laserdiodes with extreme narrow beam divergence. In addition we demonstrate a steering of the beam emission angle by changing the wavelength of the laser light.
