Structured Optical Fields Reveal Nanoscale Chiral Light-Matter Interactions Governed by Optical Chirality
Atsushi Kamegaya, Shun Hashiyada, Yoshito Y. Tanaka
Optical chirality has been proposed as the local electromagnetic quantity governing chiral light-matter interactions, yet in conventional circularly polarized fields its magnitude…
Real-Space Double Crossing Reveals Symmetry-Driven Dispersion Back-Bending of Surface Phonon Polaritons on α-Quartz
Ryoga Odawara, Kotaro Shirahata, Aozora Ohi +2
Surface phonon polaritons (SPhPs) in anisotropic crystals exhibit direction-dependent propagation and dispersion, yet how their dispersion back-bending manifests in real space has…
Unveiling orbital optical chirality through multipolar chiral light-matter interaction
Shun Hashiyada, An'an Wu, Yoshito Y. Tanaka
Chiral light-matter interactions have traditionally been understood in terms of electric-magnetic dipolar interference driven by light with spin angular momentum. Here, we show tha…
Conservation law for angular momentum based on optical field derivatives: Analysis of optical spin-orbit conversion
Shun Hashiyada, Yoshito Y. Tanaka
We present a theoretical framework for analyzing the loss of optical angular momentum (AM), including spin (SAM) and orbital (OAM) components, in light-matter interactions. Convent…
Symmetry control of strong chiral light matter interactions in photonic nanocavities for efficient circularly polarised emission
Rahul Kumar, Ben Trodden, Anastasiia Klimash +6
Chiral excited electronic states of molecules have an intrinsic sense of handedness, or twist, and are the active component in energy efficient display technologies and in new phot…
Near-field Probing of Optical Superchirality for Enhanced Bio-detection
Victor Tabouillot, Rahul Kumar, Paula L. Lalaguna +8
Nanophotonic platforms in theory uniquely enable < femtomoles of chiral biological and pharmaceutical molecules to be detected, through the highly localised changes in the chiral a…
