Research interests

The Photonic Crystals Group is a multidisciplinary team doing basic research in photonic crystals and related systems. While Materials Science is capital in our research some Fundamental Physics aspects are also central.

Our main interest is photonic crystals, which we realize by means of opals. We cover the synthesis and processing of materials and study light transport, generation and interference in ordered and disordered dielectric structures.

    Ordered Photonics
    Photonic crystals and photonic bandgaps

    Photonic Crystals represent a unique and versatile class of optical devices for manipulating the electromagnetic fields associated with light

    Disordered Photonics

    Photonic glasses and light diffusion

    Light diffusses in disordered media. Photonig glasses are dispersive disordered assembly of monodisperse spheres.

    Ordered Photonics

    Composites by Atomic Layer and Chemical Vapour deposition

    Opals can be infiltrated with other materials to obtain inverse or composite with higher refractive indx, different structures or additional properties like light generation, photo-swithching or thermo-switching.

    Nanoparticle infiltration

    Nanoparticle and Quantum Dots infiltration

    Opals are perfect hosts to infiltrate guest particles in order to control their optical properties by engineering the optical modes.


    Linear and Non-linear Spectroscopy of Photonic structrures

    Spectral transmission and reflection, band-diagrams and non-linear spectroscopy

    Random Lasing

    Random Lasing and 3D-mode lasing

    a special kind of laser with no coherent feedback, in which 3D diffusive or in general volume modes lase when stimulated emission dominates
