Measurement of two-point coherence functions of electromagnetic optical fields and applications of optical coherence
Bhaskar Kanseri, Deepa Joshi
For stationary light fields, manifestation of statistical properties such as coherence and polarization are attributed to the same physical phenomena, i.e. correlations in fluctuat…
Coherence-induced Polarization Effects in Vector Vortex Beams
Stuti Joshi, Saba N Khan, Manisha +2
We demonstrate theoretically and experimentally coherence-induced polarization changes in generic and higher-order vector vortex beams with polarization singularity. The prominent…
Degree of polarization of a spectral electromagnetic Gaussian Schell-model beam passing through 2-f and 4-f lens systems
Rajneesh Joshi, Bhaskar Kanseri
Spectral electromagnetic Gaussian Schell-model (SEGSM) beam is a generalization of Gaussian Schell model beam having parameters with spectral dependence, which offers a basic class…
Observation of geometric phase for unpolarized and partially polarized light fields
Bhaskar Kanseri, Rohit Gupta
Geometric phase, owing to its topological nature and properties of fault tolerance, plays an important role in devising real world applications in both classical and quantum domain…
Investigation of longitudinal spatial coherence for electromagnetic optical fields
Bhaskar Kanseri, Gaytri Arya
For light fields, the coherence in longitudinal direction is governed by both the frequency spectra and angular spectra they possess. In this work, we develop and report a theoreti…
Experimental Observation of Invariance of Spectral Degree of Coherence with Change in Bandwidth of Light
Bhaskar Kanseri, Hem Chandra Kandpal
An experimental study is conducted to show the effect of the change in bandwidth of light on the spectral degree of coherence at a pair of points in the cross-section of a beam. Fo…
