Description

Colloquia: Halina Rubinsztein-Dunlop, University QLD

Structured light has emerged as the tool of choice for the production of configurable and flexible confining potentials at the micron-scale. Extensive research has been conducted on the use of structured light in the fields such as optical laser micromanipulation, imaging and quantum atom optics. It provides means of production of ever more complex potential landscapes and enables an extreme flexibly. It provides means of producing a large variety of optical angular momentum beams. A direct measurement of optical angular momentum for highly focused beams is difficult. In this talk I will present overview of methods that have been used for these types of measurements and describe a new direct quantitative measurement of the orbital angular momentum in non-paraxial geometry. We study the coupling between the spin and orbital angular momentum. We also investigate, both theoretically and experimentally optimal geometries of these beams to couple to optimally designed microstructures and their applications in studies of biological and bioanalog systems.
