A Collective Propagation Law of Optical Vortex Constellations and Longitudinal Sensing
Niladri Modak, Rafael F. Barros, Marco Ornigotti +1
Optical vortices are ubiquitous phenomena naturally appearing in wave physics, yet higher-order charges inherently split into constellations of lowest-order singularities at the sm…
Tunable spatio-spectral Target Skyrmions and topological multiplexing
Pedro Ornelas, Niladri Modak, Oussama Korichi +3
Optical Skyrmions have recently garnered much interest providing a potential avenue for high capacity, robust topological information transfer. Typically, Skyrmions are derived fro…
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…
Inhomogeneous Polarization Transformation Reveals PT-Transition in non-Hermitian Optical Beam Shift
Niladri Modak, Swain Ashutosh, Shyamal Guchhait +5
Despite its non-Hermitian nature, the transverse optical beam shift exhibits both real eigenvalues and non-orthogonal eigenstates. To explore this unexpected similarity to typical…
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…
Tunable giant two-dimensional optical beam shift from a tilted linear polarizer
Niladri Modak, Sayantan Das, Priyanuj Bordoloi +1
We demonstrate an intriguing giant optical beam shift in a tilted polarizer system analogous to the Imbert-Fedorov shift in partial reflection around the Brewster's angle of incide…
Interferometric weak value of polarization observable and differential Jones matrix algebra
Niladri Modak, Sayantan Das, Priyanuj Bordoloi +1
The quantification of simultaneously present weak polarization anisotropy effects are of practical interest from polarimetric and metrological perspective. Recently, in Phys. Rev.…
A Generalized framework of weak value amplification in path interference of polarized light for the enhancement of all possible polarization anisotropy effects
Niladri Modak, Athira B S, Ankit Kumar Singh +1
Using the profound interferometric philosophy of weak value amplification, we propose a simple, general and a robust polarization method for the amplification and quantification of…
Weak value amplification using spectral interference of Fano resonance
Shyamal Guchhait, Athira B S, Niladri Modak +4
The extraordinary concept of weak value amplification and a number of other seemingly counter-intuitive wave phenomena are manifestations of fine interference effects. Taking examp…
