Congratulations to 4th year PGR Kishan Menghrajani, who is lead author on ‘Vibrational strong coupling with surface plasmons and the presence of surface plasmon stop bands’, published in ACS Photonics.
The authors present results from experiments and numerical simulations to show that surface plasmon modes provide convenient open cavities for vibrational strong coupling experiments. In addition to providing momentum matching between surface plasmon modes and incident light, gratings may also produce a modification of the surface plasmon properties, notably their dispersion. The authors further show that for the parameters used in our experiment, surface plasmon stop bands are formed, and they find that both stop-band edges undergo strong coupling.
Kishan’s previous publications include ‘Hybridization of Multiple Vibrational Modes via Strong Coupling Using Confined Light Fields’.
