Emerging Aspects of Optical Beam Shifts

Abstract

We indicate the possible expansion of the domain of optical beam shits to demonstrate exotic physical effects, such as, demonstration of joint correlation of the beam shifts, and mimicking PT symmetric systems.

Position-position classical entanglement realized through optical beam shifts

“…8 Although the shifts are of fundamentally different origin, we have recently shown that the beam shifts are inherently non-separable, and such non-separability becomes tangible only in certain regions of the corresponding parameter space. 9 In this work, we experimentally demonstrate the realization of this non-separability as a position-position classically entangled state by taking a polarized Gaussian beam reflected from an air-glass interface as a a tunable position-position classically entangled state. We anticipate that the manifestation of discussed entanglement will evident in a wide-range of light-matter interactions due to the ubiquitous nature of the beam shifts.…”

“…We have recently used the Pearson correlation coefficient to quantify the non-separability of the longitudinal and transverse shifts. 9 As apparent from, 9 the non-separability although inherent in the formalism of the beam shifts, is only be detectable at certain regions of the corresponding experimental parameter space. For horizontal input polarization state, non-separability becomes noticeable for angles of incidence near θ i → Brewster's angle.…”
