About
Anderson Monteiro Amaral
I am a physicist at the Departamento de Física, Universidade Federal de Pernambuco (UFPE), working on nonlinear and quantum optics, structured light, and nanophotonics. My research spans the fundamentals and applications of the orbital angular momentum of light, nonlinear light–matter interaction in complex media, and luminescent nanomaterials — together with the instrumentation and measurement methods that make those experiments possible.

Academic background
Scientific interests
Angular momentum of light and optical vortices. Light can carry orbital angular momentum. When this momentum circulates around a point, the beam hosts an optical vortex. I study how to characterize and shape such beams — including vortices with arbitrary, non-cylindrical geometries — with applications from optical tweezers to plasmonics.
Nonlinear optics. For sufficiently intense light, a material’s optical response is no longer proportional to the input, and a rich variety of phenomena appear. I work on nonlinear refraction, absorption, and scattering — and on methods to measure them reliably in turbid and resonant media.
Nanophotonics & plasmonics. Metallic nanostructures can confine and enhance optical fields, and luminescent rare-earth nanomaterials enable sensing and nanothermometry. I study these systems both for nonlinear optics and for practical measurement applications.
