THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:

Structured light for computation and light conversion

PhD Nara Rubiano da Silva

Postdoc fellow – GIQSul – UFSC


Structured light displays intricate field distributions (of intensity, phase, polarization) in space, with several emerging applications. In the Quantum Optics Laboratory at UFSC, we study classical and quantum processes utilizing such optical fields. In this talk, I will present two of our recent results in the classical regime. Firstly, we manipulate the phase of light for realizing a computational task, namely, a matrix-by-vector multiplication. Each matrix or vector element is mapped into the tranverse phase distribution of the light beam, and the required operations are realized by optical elements. I will introduce this optical processor and, as an example, its application to an optimization problem called unidimensional Distance Geometry Problem. In a second work, we investigate a fundamental aspect of employing structured beams of the Laguerre-Gauss family in stimulated parametric down-conversion. Specifically, we analyse the selection rules involving the radial order of the resulting LG beams, which I will discuss in my talk.
