aperture diffraction beam shaping
2011/5/6
We analyze optical diffraction of a micro-aperture (slit or hole) in a metal screen in the intermediate zone and report its application for beam focusing and collimating in micro-optics. Both finite-d...
An impact of a localization of an oxide aperture within a vertical-cavity surface-emitting diode laser (VCSEL) cavity on its lasing threshold
semiconductor laser vertical-cavity surface-emitting diode laser (VCSEL)
2011/4/27
In the present paper, an impact of localization of an oxide aperture within a vertical-cavity surface-emitting diode laser (VCSEL) on its threshold operation is analyzed. As expected, a shift of the a...
