Surface emitting semiconductor laserdiodes based on surface mode emission

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...

Zusammenfassung: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.
