Photonic Crystal Fibers

Our group studies the myriad phenomena encountered by the manipulation of fundamental properties of light, with the aim of developing next generation photonic devices. For example, complex, nano-structured photonic devices can be used to slow light (by confining photons in time) or counteract diffraction (by confining photons in space). Some confinement geometries lead to spatially complex beams that possess intriguing properties such as the ability of optical vortices to carry orbital angular momentum or the ability of Bessel beams to self-heal.
