High-angle optically accessible Brewster cavity exciton-polaritons

Abstract

We report on the observation of the strong-coupling regime between quantum well excitons and a high incidence "Brewster cavity mode" previously identified as the generalized Brewster angle condition in multilayer structures [H. F. Mahlein, J. Opt. Soc. Am. 64, 647 (1974)]. This propagating mode is inside the light cone and therefore can be accessed from the top side of the sample without the need for prism or grating coupling methods. The observed anticrossing is clear evidence of the strong light-matter coupling regime. All the results are accurately reproduced by transfer matrix simulations. These results demonstrate the high potential of such structures for the study of propagating polaritons at high k, which could be harnessed for the realization of polaritonic circuit devices.

Time domain photonic hook beam for manipulating nanoparticles along curved trajectories

“…Dielectric with refractive index of 1.41 and sector angle about of 90 degree used in simulations 28 . Simulations have shown that the greatest beam curvature can be obtained when the remote segment is irradiated near the Brewster angle 30 . Combining key parameters of the photonic hook, and having in mind the quality criteria for the photonic jet 31 , we propose to characterize the PH by a quality criterion Q as…”
