Postdoctoral Research Associate/Fellow
Spatiotemporal properties of light in multimode optical fibre
School of Information Technology and Electrical Engineering (ITEE), The University of Queensland, Brisbane, Australia.
We seek applications from suitably qualified candidates who will focus on the development of optical systems for the measurement and manipulation of the spatial, spectral and temporal properties of light in multimode optical fibre. The position is funded under an Australian Research Council (ARC), Discovery Project in collaboration with the University of Southampton and industrial partners Nokia (Bell Labs, US) and Finisar Australia.

[tutorial] Setting up a DMD: Diffraction effects
I recently acquired a Digital Micromirror Device (DMD) and when I started setting up the experiment, I faced a problem I did not anticipate which is closely related to blazed gratings. Due to the fact that the surface of a DMD is not flat, diffraction orders are shiffted compared to the optical axis. This shift depends on the pixel pitch, the wavelength and the incident angle. A close look at this diffraction phenomenon is important to configure an experimental setup properly. It is even relevant to consider this effect before chosing the appropriate DMD model to buy.

[tutorial] Control a Vialux DMD with Python
Vialux provides Texas Instrument DMD (Digital MicroMirror Devices) chips with an electronic board to send and display image sequences at high speed (up to 30kHz). While they provide a C++ dll, Labview and Matlab codes, I did not find any tool for Python. I share here a simple module that wraps the C++ functions for Python. It allows to use in a simple manner the basic functions while providing the advanced features of the ALP API.

[tutorial] Easy generation of Laguerre Gauss beam with Python and an SLM
I want to share a simple Python writen by José Salazar-Serrano. This program aims to generate a Laguerre Gauss beam with a phase only spatial light modulator (SLM). It uses the slmPy and requires the wxPython and opencv modules to run. The full description of the package and the files are available on the Github repository.
