Scientific Research

My principal research interest lies on the study of phenomena resulting from the interaction of light and matter in diverse micro-/nano-structures, and the development of novel photonic devices with compact geometries and miniaturized footprints based on such effects. Some of the topics currently being investigated include:
    

    1. Crystalline waveguide-based lasers and nonlinear optical frequency converters.

    2. Ferroelectric thin films for integrated optics.

    3. Femtosecond laser and energetic ion induced material modifications in crystalline materials.

    4. Mie-resonant dielectric metasurfaces for nonlinear nanophotonics.

    5. Plasmonic nanostructures for strong light-matter interaction.
