Realization of joint weak measurement in classical optics using optical beam shifts
Ritwik Dhara, Shyamal Guchhait, Meghna Sarkar +3
Quantum weak measurements became extremely popular in classical optics to amplify small optical signals for fundamental interests and potential applications. Later, a more general…

Signum phase mask differential microscopy
Jeeban Kumar Nayak, Niladri Modak, Sayan Ghosh +1
We propose and experimentally demonstrate a differential microscopy method to obtain simultaneous amplitude, phase, and quantitative polarization gradient imaging in a single exper…

Non-separable Optical Beam Shifts and Emergence of Position-position Classical entanglement
Niladri Modak, S Ashutosh, Shyamal Guchhait +3
Under the introduction of any interface in its trajectory, an optical beam experiences polarization-dependent deflections in the longitudinal and transverse directions with respect…
