Direct transfer of pump amplitude to parametric down-converted photons
Ali Anwar, Pravin Vaity, Chithrabhanu Perumangatt +1
We numerically and experimentally show that all photons generated by spontaneous parametric down-conversion (SPDC) follow a transverse amplitude similar to that of the pump. This a…
Divergence of optical vortex beams
Salla Gangi Reddy, Chithrabhanu P, Shashi Prabhakar +3
We show, both theoretically and experimentally, that the propagation of optical vortices in free space can be analysed by using the width () of the host Gaussian beam and the…
Measuring Mueller matrix of an arbitrary optical element with a fixed set of polarization optics
Salla Gangi Reddy, Shashi Prabhakar, A. Aadhi +4
We have described a novel way to determine the Mueller matrix of any optical element by using projection method. For this purpose, we have used two universal SU(2) gadgets for pola…
