Abstract


We report on our recent results on metal-dielectric-metal microcavities with small effective volume for enhanced light matter interaction. These periodic sub-wavelength structures cover only 25% of the surface and yet absorb more than 80% of the impinging radiation, thanks to a near field mechanism. By inserting within these microcavities quantum wells we were able to attain the ultra-strong light matter regime.
