Our group is interested in the field of singular optics and its applications. Singular optics is a branch of optics which deals with the study of the optical fields with undefined phase (scalar) or polarization (vector). Our group is working on linear, nonlinear, scalar and vector singular optics. We are generating and characterizing the singular optical beams such as optical vortex (OV) beams with integer and fractional charge. We are also generating the polarization singularities based on crystal optics and investgate their usefulness in different applications such as optical trapping and optical communications. We are also using another class of optical fields with nested phase singularities, speckle fields to recover the object information lying behind a birefringent scatterer. Our group is also interested in the generation and applications of filamentation in condensed transparent media using femtosecond laser.
