Controlling the evolution of nondiffracting speckle by complex amplitude modulation on a phase-only spatial light modulator

Author: Dudley, Angela L ; Vasilyeu, R ; Belyi, V ; Khilo, N ; Ropot, P ; Forbes, A Date: Sep 2011 In this work we investigate the structure of nondiffracting speckle fields, both experimentally and theoretically. We are able to produce very good agreement between the experimentally recorded and theoretically calculated fields by using ... Read more
The generation of flat-top beams by complex amplitude modulation with a phase-only spatial light modulator

Author: Hendriks, A ; Naidoo, Darryl ; Roux, FS ; Löpez-Mariscal, C ; Forbes, A Date: Aug 2012 Phase-only spatial light modulators are now ubiquitous tools in modern optics laboratories, and are often used to generate so-called structured light. In this work we outline the use of a phase-only spatial light modulator to achieve full ... Read more
Multiplexing of spatial modes in the mid-IR region

Author: Gailele, Lucas M ; Maweza, Elijah L ; Dudley, Angela L ; Ndagano, B ; Rosales-Guzman, C ; Forbes, A Date: Feb 2017 Traditional optical communication systems optimize multiplexing in polarization and wavelength both transmitted in fiber and free-space to attain high bandwidth data communication. Yet despite these technologies, we are expected to reach a ... Read more
