Designing interferometers within a single optical beam
Bereneice Sephton, Rakhi Thomas, Carlo Schiano +8
Interferometry provides highly sensitive access to optical phase and is central to much of modern metrology and phase imaging methods. Conventional implementations, however, often…
Remote engineering of particle-like topologies to visualise entanglement dynamics
Fazilah Nothlawala, Bereneice Sephton, Pedro Ornelas +6
Skyrmions are a particle-like topology with a quantised skyrmion number, realised across condensed matter and photonic platforms alike. In quantum photonics, they constitute an eme…
Programmable non-Hermitian photonic quantum walks via dichroic metasurfaces
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +6
The evolution of a closed quantum system is described by a unitary operator generated by a Hermitian Hamiltonian. However, when certain degrees of freedom are coupled to an environ…
An experimental technique for measuring radial coherence
Radhika Prasad, Nilakshi Senapati, Suman Karan +4
Coherence refers to correlations between field vibrations at two separate points in degrees of freedom such as space, time, and polarisation. In the context of space, coherence the…
Electrically tunable liquid-crystal metasurfaces with patterned birefringence and dichroism
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +7
Light propagation through artificially patterned anisotropic materials, such as dielectric metasurfaces, enables precise control of the spatio-vectorial properties of optical field…
