Abstract
We experimentally demonstrate collective amplified modes along bent chains of directly coupled, amplifying spherical microdroplet resonators. The chains, comprising similar to 40 non-contacting resonators, were bent through angles up to similar to 25 degrees. The modal probability of the system shows a sharp drop upon bending through small angles (similar to 10 degrees), and thereafter changes minimally under further bending. The frequency response is significantly maintained under bending. We numerically study the transmittance of a chain of non-contacting amplifying resonators using finite-difference-time-domain calculations, and observe that nanojet filamentation influences coupling at the bend. A self-correcting mechanism of propagation is observed, originating from the lensing effect of the spherical resonator. (C) 2013 AIP Publishing LLC.
