Quasinormal mode analysis of chiral power flow from linearly polarized dipole emitters coupled to index-modulated microring resonators close to an exceptional point
Juanjuan Ren, Sebastian Franke, Stephen Hughes
Chiral emission can be achieved from a circularly polarized dipole emitter in a nanophotonic structure that possess special polarization properties such as a polarization singulari…
Chiral quantum optics in broken-symmetry and topological photonic crystal waveguides
Nils Hauff, Stephen Hughes, Hanna Le Jeannic +2
On-chip chiral quantum light-matter interfaces, which support directional interactions, provide a promising platform for efficient spin-photon coupling, non-reciprocal photonic ele…
Strong coupling regime and hybrid quasinormal modes of a single plasmonic resonator coupled to a TMDC monolayer
Chelsea Carlson, Robert Salzwedel, Malte Selig +2
We present a rigorous photonic mode model to describe the strong coupling between a monolayer of and a single gold nanoparticle. The onset of strong coupling is quanti…
Fermi's golden rule for spontaneous emission in absorptive and amplifying media
Sebastian Franke, Juanjuan Ren, Marten Richter +2
We demonstrate a fundamental breakdown of the photonic spontaneous emission (SE) formula derived from Fermi's golden rule, in absorptive and amplifying media, where one assumes the…
Quasinormal modes and Purcell factors of coupled loss-gain resonators and index-modulated ring resonators near exceptional points
Juanjuan Ren, Sebastian Franke, Stephen Hughes
We first present a quasinormal mode (QNM) theory for coupled loss-gain resonators working near an exceptional point. Assuming linear media, which can be fully quantified using the…
Inverse design of broadband and lossless topological photonic crystal waveguide modes
Eric Nussbaum, Erik Sauer, Stephen Hughes
Topological photonic crystal waveguides can create edge states that may be more robust against fabrication disorder, and can yield propagation modes below the light line. We presen…
