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…
Weak value amplification using asymmetric spectral response of Fano resonance as a natural pointer
Ankit K. Singh, Subir K. Ray, Shubham Chandel +4
Weak measurement enables faithful amplification and high precision measurement of small physical parameters and is under intensive investigation as an effective tool in metrology a…
