A Semiconductor Topological Photonic Ring Resonator

M. Jalali Mehrabad, A. P. Foster, R. Dost +6

Unidirectional photonic edge states arise at the interface between two topologically-distinct photonic crystals. Here, we demonstrate a micron-scale GaAs photonic ring resonator, c…

Broadband conversion of microwaves into propagating spin waves in patterned magnetic structures

F. B. Mushenok, R. Dost, C. S. Davies +4

We have used time-resolved scanning Kerr microscopy (TRSKM) and micromagnetic simulations to demonstrate that, when driven by spatially uniform microwave field, the edges of patter…

Topological and conventional nano-photonic waveguides for directional integrated quantum optics

N. J Martin, M. Jalali Mehrabad, X. Chen +12

Chirality in integrated quantum photonics has emerged as a promising route towards achieving scalable quantum technologies with quantum nonlinearity effects. Topological photonic w…

A chiral topological add-drop filter for integrated quantum photonic circuits

M. Jalali Mehrabad, A. P. Foster, N. J. Martin +5

The integration of quantum emitters within topological nano-photonic devices opens up new avenues for the control of light-matter interactions at the single photon level. Here, we…

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…

Nonlinear Quantum Optics at a Topological Interface Enabled by Defect Engineering

L. Hallacy, N. J. Martin, M. Jalali Mehrabad +11

The integration of topology into photonics has generated a new design framework for constructing robust and unidirectional waveguides, which are not feasible with traditional photo…
