Metamaterial photonic funnels for subdiffraction light compression and propagation
Metamaterial photonic funnels for subdiffraction light compression and propagation
We present waveguides with photonic crystal cores, supporting energy propagation in subwavelength regions with a mode structure identical to that in telecom fibers and develop an analytical description of light transmission through these systems. We design metamaterials for near-, mid-, and far-IR frequencies, and demonstrate $\ensuremath{\sim}10\ensuremath{\cdots}30%$ energy transfer to and …
