Complex far fields and optical singularities due to propagation beyond tight focusing: combined effects of wavefront curvature and aperture diffraction

Nitish Kumar, Anirban Debnath, Nirmal K. Viswanathan

All optical systems, which involve the collimation of a reflected, transmitted or scattered wave subsequent to tight focusing, are subject to two kinds of deviations. One is the wa…

Measurement of Orbital Angular Momentum of Light using Stokes Parameters and Barnett's Formalism

Anirban Debnath, Nirmal K. Viswanathan

We present a formalism for experimental determination of the orbital angular momentum (OAM) of a paraxial optical beam-field by intertwining Barnett's formalism and Stokes paramete…
