Background: Weak measurement involves weak coupling between the system and the measuring device (pointer) enables large amplification and high precision measurement of small physical parameters. The outcome of this special measurement procedure invol

The extraordinary concept of weak value amplification can be formulated within the realm of wave interference as nearly destructive interference between the eigenstates of the measuring observable. Here we report on a phenomenon of interferometric we

In this paper, we study parametric optical rectification that is not due to material properties but emerges from the electrostatic near-field interaction between nanosized metallic domains. The ability to demonstrate this effect comes from samples ba

We experimentally study the optical second-harmonic generation (SHG) from deep subwavelength gold-silver heterodimers, and silver-silver and gold-gold homodimers. Our results indicate a heterodimer SHG that is an order of magnitude more intense than

Spin–orbit interaction deals with the interaction and coupling of spin and orbital angular momentum degrees of freedom of spinning particles, which manifests in diverse fields of physics, ranging from atomic, condensed matter to optical systems. In

A light beam carrying a spatially varying state of polarization generates a space-varying Pancharatnam-Berry geometric phase while propagating through a homogeneous anisotropic medium. We show that determination of such a space-varying geometric phas

The spatial and the angular variants of the Imbert-Federov (IF) beam shifts and the angular Goos-Hanchen (GH) shift contribute in a complex interrelated way to the resultant beam shift in partial reflection at planar dielectric interfaces. Here, we s

For an azimuthally symmetric space varying polarization state, spin dependent rotation of azimuthal lobes of the beam is observed in homogeneous anisotropic medium, which is the manifestation of rotational spin Hall effect of light.
