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…
