We have just posted a paper on arXiv describing a potential new criterion for strong light-matter coupling using spectroscopic ellipsometry. Strongly coupled systems are usually characterised using intensity data (transmittance, reflectivity, etc). Spectroscopic...

This is the lab where we do our Fourier imaging/spectroscopy, where the data we need to compile our cherished dispersion diagrams are acquired. Well it was, but this picture, taken by Philip Thomas, the post-doc who set up and runs this lab, was taken on March 18th of...

APS March meeting 2020

Kishan Menghrajani set off for his first trip to the United States to attend the March APS meeting in Denver (set for March 2-6). Kishan was all set to present his work on vibrational strong coupling beyond the light line for photmat, to meet other researchers working...

Many strong-coupling experiments involve metal-based various cavity architectures to generate new eigenstates of the hybrid system. One advantage of using the plasmonic modes of individual metal nanoparticles is that such modes are dispersionless. We set out to see if...

Award of PhD to Kishan Menghrajani

Kishan Menghrajani successfully defended his PhD yesterday (October 9). Kishan’s work has been vital in developing our capability to look at strong coupling of vibrational modes. Kishan’s PhD, will soon be available on Exeter University’s repository...

We used a stack of meta-molecules based on split ring resonators (right) to mimic linear (J- and H-) aggregates. Using RF techniques we measured the dispersion of the modes (left)   Project photmat is all about linking molecules with light. We have recently added...
