Observation of Electrically Tunable Chirality Inversion in a Slow-Light Waveguide
Xuchao Chen, Savvas Germanis, Nicholas J. Martin +8
We identify chiral inversion points in slow-light, glide-plane-symmetric, photonic-crystal waveguides, defined as fixed locations where the local optical chirality changes sign ove…
Controlling coherence between waveguide-coupled quantum dots
D. Hallett, J. Wiercinski, L. Hallacy +10
We present a novel waveguide design that incorporates a split-diode structure, allowing independent electrical control of transition energies of multiple emitters over a wide range…
Stark Tuning and Charge State Control in Individual Telecom C-Band Quantum Dots
N. J. Martin, A. J. Brash, A. Tomlinson +12
Telecom wavelength quantum dots (QDs) are emerging as a promising solution for generating deterministic single photons compatible with existing fiber optic infrastructure. Emission…
Chiral Quantum Optics with Scalable Quantum Dot Dimers
L. Hallacy, D. Hallett, A. Fenzl +8
We present a scalable method for electrically tuning multiple spatially separated quantum dots embedded in photonic crystal waveguides. Ion implantation into the top p-doped layer…
All-optical nonlinear phase modulation in open semiconductor microcavities
Fedor A. Benimetskiy, Paul M. Walker, Anthony Ellul +8
We report a significant advancement in ultra low power light-by-light phase modulation using open semiconductor microcavities in the strong light-matter coupling regime. We achieve…
Flat-band compactons in a two-dimensional driven-dissipative Lieb lattice
Seth Lovett, Paul M. Walker, Anthony Ellul +3
We experimentally study the effect of inter-particle interactions on the flat-band states of a two-dimensional Lieb lattice with drive and dissipation. Exploiting the giant nonline…
