First-order optical system design and linear canonical transformations
Our main research line comprises the generation of laser beams (either using holography or specific optical transformations) as well as their optical characterization. It implies the development of techniques and experimental setups in the field of phase space optics. For instance, the fractional Fourier transform is a well-known operation from which the reconstruction of the Wigner distribution (WD) of the beam can be obtained. Indeed, the WD provides a complete characterization of the beam.
We have developed advanced optical systems capable to perform important operations such as gyrator and the Fractional Fourier transformations. These systems are optimal because a minimum number of optical elements are required. Moreover they are programmable following user input interactively.
