High-frequency acousto-optic effects in Bragg reflectors (2014)
Journal Article
Farmer, D., Akimov, A. V., Gippius, N., Bailey, J., Sharp, J. S., & Kent, A. (2014). High-frequency acousto-optic effects in Bragg reflectors. Optics Express, 22(12), 15218-15231. https://doi.org/10.1364/OE.22.015218

Picosecond acoustic interferometry was used to study the acousto-optic properties of a distributed Bragg reflector (DBR) manufactured from two immiscible polymers (cellulose acetate and polyvinylcarbyzole). Picosecond strain pulses were injected into... Read More about High-frequency acousto-optic effects in Bragg reflectors.

III-V semiconductor waveguides for photonic functionality at 780 nm (2014)
Journal Article
Maclean, J. O., Greenaway, M. T., Campion, R. P., Pyragius, T., Fromhold, T. M., Kent, A. J., & Mellor, C. J. (2014). III-V semiconductor waveguides for photonic functionality at 780 nm. Proceedings of SPIE, 8988, Article 898805. https://doi.org/10.1117/12.2039898

Photonic integrated circuits based on III-V semiconductor polarization-maintaining waveguides were designed and fabricated for the first time for application in a compact cold-atom gravimeter1,2 at an operational wavelength of 780 nm. Compared with o... Read More about III-V semiconductor waveguides for photonic functionality at 780 nm.

Dynamics of a vertical cavity quantum cascade phonon laser structure (2013)
Journal Article
Maryam, W., Akimov, A. V., Campion, R., & Kent, A. (2013). Dynamics of a vertical cavity quantum cascade phonon laser structure. Nature Communications, 4, Article 2184. https://doi.org/10.1038/ncomms3184

Driven primarily by scientific curiosity, but also by the potential applications of intense sources of coherent sound, researchers have targeted the phonon laser (saser) since the invention of the optical laser over 50 years ago. Here we fabricate a... Read More about Dynamics of a vertical cavity quantum cascade phonon laser structure.
