Resonator with orthogonally polarized dual wavelength output based on layered anisotropic metamaterials

The transmission properties of a resonator based on one air layer sandwiched by two-layered anisotropic metamaterials with different negative-permittivity tensors are studied through analytical analysis and numerical calculations. The resonator has orthogonally polarized dual wavelength output. The difference of the two wavelengths can be adjusted through changing the permittivity tensors, and the ratio of the intensities of the two orthogonally polarized waves can also be adjusted through changing the polarization direction of incident wave. The study results may find applications in the design of laser resonator.
