Full-Field Terahertz Imaging at Kilohertz Frame Rates Using Atomic Vapor (2020)
Journal Article
Downes, L. A., MacKellar, A. R., Whiting, D. J., Bourgenot, C., Adams, C. S., & Weatherill, K. J. (2020). Full-Field Terahertz Imaging at Kilohertz Frame Rates Using Atomic Vapor. Physical Review X, 10(1), Article 011027. https://doi.org/10.1103/physrevx.10.011027

There is much interest in employing terahertz (THz) radiation across a range of imaging applications, but so far, technologies have struggled to achieve the necessary frame rates. Here, we demonstrate a THz imaging system based upon efficient THz-to-... Read More about Full-Field Terahertz Imaging at Kilohertz Frame Rates Using Atomic Vapor.

Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen-Back regime (2018)
Journal Article
Mathew, R. S., Ponciano-Ojeda, F., Keaveney, J., Whiting, D., & Hughes, I. (2018). Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen-Back regime. Optics Letters, 43(17), 4204-4207. https://doi.org/10.1364/ol.43.004204

We demonstrate a technique to lock simultaneously two laser frequencies to each step of a two-photon transition in the presence of a magnetic field sufficiently large to gain access to the hyperfine Paschen–Back regime. A ladder configuration with th... Read More about Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen-Back regime.

Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen–Back regime (2017)
Journal Article

We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S1/2,5P1/2,5P3/25S1/2,5P1/2,5P3/2 and 5D3/25D3/2 terms) in a thermal vapour of 87Rb87Rb atoms. We investigate the 4WM spectra u... Read More about Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen–Back regime.

Single-photon interference due to motion in an atomic collective excitation (2017)
Journal Article
Whiting, D. J., Šibalić, N., Keaveney, J., Adams, C. S., & Hughes, I. G. (2017). Single-photon interference due to motion in an atomic collective excitation. Physical Review Letters, 118(25), Article 253601. https://doi.org/10.1103/physrevlett.118.253601

We experimentally demonstrate the generation of heralded bi-chromatic single photons from an atomic collective spin excitation (CSE). The photon arrival times display collective quantum beats, a novel interference effect resulting from the relative m...
