| Description | Please see the key Findings description provided for EP/R04399X/1 Within the Oxford group we made progress in the laser-induced modification of dielectric mirrors, intended as a method for the post-fabrication fine-tuning of microcavity resonances that is needed for polariton lattices using open cavity arrays. We were able to controllably modifify the refractive index of coating layers using 300 fs laser pulses (780 nm) in such a way that in-situ tuning might be possible. This fell short of the goal of demonstrating tuning of a 2-D cavity array to within the exciton linewidth. To advance complementary ideas of quantum simulation using microcavity systems we participated in collaborations with groups at Imperial College and AMOLF in the Netherlands, which led to high profile papers on photonic Bose Einstein Condensates and stochastic resonance in nonlinear systems respectively. |
| Exploitation Route | There is still more to do on the post-fabrication tuning of open microcavities and the techniques being pursued here remain worthy of further work. |
