Modelling spectra of hot alkali vapour in the saturation regime (2025)
Journal Article
Häupl, D. R., Higgins, C. R., Pizzey, D., Briscoe, J. D., Wrathmall, S. A., Hughes, I. G., Löw, R., & Joly, N. Y. (2025). Modelling spectra of hot alkali vapour in the saturation regime. New Journal of Physics, 27, Article 033003. https://doi.org/10.1088/1367-2630/adb77c

Laser spectroscopy of hot atomic vapours has been studied extensively. Theoretical models that predict the absolute value of the electric susceptibility are crucial for optimising the design of photonic devices that use hot vapours, and for extractin...

Fine-structure changing collisions in 87 Rb upon D 2 excitation in the hyperfine Paschen-Back regime (2024)
Journal Article
Higgins, C. R., Pizzey, D., & Hughes, I. G. (2024). Fine-structure changing collisions in 87 Rb upon D 2 excitation in the hyperfine Paschen-Back regime. Journal of Physics B: Atomic, Molecular and Optical Physics, 57(23), Article 235002. https://doi.org/10.1088/1361-6455/ad8ab0

We investigate fine structure changing collisions in 87Rb vapour upon D2 excitation in a thermal vapour at 75 ∘C; the atoms are placed in a 0.6 T axial magnetic field in order to gain access to the hyperfine Pashen-Back regime. Following optical exci... Read More about Fine-structure changing collisions in 87 Rb upon D 2 excitation in the hyperfine Paschen-Back regime.

Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen–Back regime (2021)
Journal Article
Higgins, C. R., & Hughes, I. G. (2021). Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen–Back regime. Optics Letters, 54(16), Article 165403. https://doi.org/10.1088/1361-6455/ac20be

We observe electromagnetically induced transparency (EIT) in a V-system in a thermal rubidium-87 vapour in the hyperfine Paschen-Back regime, realised with a 0.6 T axial magnetic field. In this regime energy levels are no longer degenerate and EIT fe... Read More about Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen–Back regime.

Atomic line vs. lens cavity filters: A comparison of their merits (2020)
Journal Article
Higgins, C. R., Pizzey, D., Mathew, R. S., & Hughes, I. G. (2020). Atomic line vs. lens cavity filters: A comparison of their merits. OSA continuum, 3(4), 961-970. https://doi.org/10.1364/osac.390604

We present a comparison between lens cavity filters and atomic line filters, discussing their relative merits for applications in quantum optics. We describe the design, characterization, and stabilization procedure of a lens cavity filter, which con... Read More about Atomic line vs. lens cavity filters: A comparison of their merits.
