By performing a full analysis of the projected local density of states (LDOS) in a photonic crystal waveguide, we show that phase plays a crucial role in the symmetry of the light-matter interaction. By considering a quantum dot (QD) spin coupled to a photonic crystal waveguide (PCW) mode, we demonstrate that the light-matter interaction can be asymmetric, leading to unidirectional emission and a deterministic entangled photon source. Further we show that understanding the phase associated with…

A photonic interface of chiral cavity quantum electrodynamics
Cavity quantum electrodynamics studies light-matter interactions at single quanta level. Chiral photon-emitter coupling in photonic structures is characterized as unidirectional propagation locked by…
Engineering chiral light–matter interaction in photonic crystal waveguides with slow light
We design photonic crystal waveguides with efficient chiral light–matter interfaces that can be integrated with solid-state quantum emitters. By using glide-plane-symmetric waveguides, we show that…

Engineering Chiral Light–Matter Interactions in a Waveguide-Coupled Nanocavity
Spin-dependent, directional light–matter interactions form the basis of chiral quantum networks. In the solid state, quantum emitters commonly possess circularly polarized optical transitions with…

TLDR
This article explores the transition from travelling to standing waves for two different photonic crystal waveguide designs and finds that time-reversal symmetry and the reciprocal nature of light places constraints on using C-points in the slow-light regime.
Chiral interactions of quantum dots embedded within nanophotonic waveguides
This thesis describes the couplings and interactions of quantum dots embedded within nanoscale photonic waveguides. Optical spectroscopic measurements were performed on these devices for the…
Spin-dependent directional emission from a quantum dot ensemble embedded in an asymmetric waveguide.
TLDR
This study examines a photonic wire waveguide embedded with an ensemble of quantum dots (QDs) that directionally emits into the waveguide depending on the spin state of the ensemble and examines a microdisk resonator with a stair-like edge that supports selective coupling of the QD ensemble radiation into a whispering gallery mode that rotates unidirectionally.
Strongly correlated photon transport in nonlinear photonic lattices with disorder: Probing signatures of the localization transition
We study the transport of few-photon states in an open disordered nonlinear photonic lattice. More specifically, we consider a waveguide quantum electrodynamics (QED) setup where photons are…
Optimised chiral light-matter interactions at polarisation singularities for quantum photonics
TLDR
The optimisation of this chiral light-matter interaction using slow-light waveguides is discussed, and designs with 8.6 times enhancement of the local density of optical states at a C-point are shown.

The Nature of Nanotechnology
TLDR
“Gene Chip” is used as an example that is still object of research in basic nanoscience, but at the same time is already of interest in the nanoengineering step and has partially even reached the technology status.
Opt
TLDR
A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.

Peer review, at its best, should aim to provide authors and editors with rigorous and constructive feedback resulting in an improved study, and there is clearly room for improvement, the current system is not broken.
