Modulation in degree of cross-polarization at Young's interferometer illuminated by non-uniformly polarized electromagnetic fields
Rajneesh Joshi, Gyaprasad
The degree of cross-polarization (DoCP) and the electromagnetic degree of coherence (EM DoC) of an electromagnetic beam are investigated at the observation points for incoherent an…

Real-time polarization tuning in Mach-Zehnder interferometer using electro-optically modulated twist angles of nematic liquid crystal Note: This paper has been accepted for publication in "Journal of Theoretical and Applied Physics"
Rajneesh Joshi, Gyaprasad
We propose a theoretical framework to dynamically control the degree of polarization of light by using the superposition of incoherent orthogonally polarized beams in a Mach-Zehnde…

Electro-optically controlled photon group velocity, temporal walk-off and two-photon entanglement via nematic liquid crystal
Gyaprasad, Rajneesh Joshi
The propagation of the quantum states of light in dispersive and anisotropic media is a fundamental problem in quantum optics. We present a unified theoretical framework for the pr…
