Based on the method of transformation optics, we show the miniaturization of a resonant cavity filled with metamaterials. Because the electromagnetic behavior in the transformation space is invariant in the original space, the quality factor Q and the resonant modes of a miniaturized resonant cavity filled with metamaterial are the same as for those in the original space. Theoretical analysis and numerical simulation confirms that the miniaturization of resonant cavities is effective.

Optical Soliton Perturbation in Nonlinear Directional Couplers

100%
Vega-Guzman J., Babatin M., Biswas A.
|
EN
This paper secures soliton solutions to optical couplers in presence of Hamiltonian perturbation terms by the aid of undetermined coefficients. Both twin core couplers and multiple core couplers are studied. Bright, dark and singular soliton solutions are obtained for the model. The existence criteria for the solitons are also presented. The study is focused to the Kerr and power laws of nonlinearity.
