Highly tunable low-threshold optical parametric oscillation in radially poled whispering gallery resonators
T. Beckmann, H. Linnenbank, H. Steigerwald +4
Whispering gallery resonators (WGR's), based on total internal reflection, possess high quality factors in a broad spectral range. Thus, nonlinear optical processes in such cavitie…

Gradient Index Metamaterial Based on Slot Elements
Oliver Paul, Benjamin Reinhard, Bernd Krolla +2
We present a gradient-index (GRIN) metamaterial based on an array of annular slots. The structure allows a large variation of the effective refractive index under normal-to-plane i…
