Research Interests

The Ramachandran Group studies the fundamental properties and applications of spatially structured light beams. Examples of such states of light include (a) Bessel beams that can self-heal through obstructions and are diffraction resistant for longer distances than conventional Gaussian beams; (b) beams carrying orbital angular momentum (OAM) that enable super-resolution microscopy or rotate microscopic particles in optical tweezer configurations. A central aim of the group is use of such beams for applications ranging from microscopy and machining to quantum telecommunications and sensing.
