Systems and methods for transmitting electromagnetic energy in a photonic device
First Claim
1. A photonic device, comprising:
- a body having a front surface and a plurality of periodic segments physically coupled together along a first direction normal to the surface, the body being receptive to an electromagnetic wave incident at a second direction oblique to the first direction and having a first frequency, each segment comprising;
a first anisotropic dielectric layer having an anisotropic axis at an angle oblique to the first direction; and
a second layer;
wherein each segment is configured such that the received wave is transmittable within the body in an axially frozen mode.

Abstract
Systems and methods are provided that allow transmission of an electromagnetic wave in and through a periodic multilayered photonic device. The photonic device preferably is a periodic stack of plane-parallel layers with at least one them displaying dielectric anisotropy with a principle anisotropic axis forming an oblique angle with the normal to the layers. The wave obliquely incident on the surface of the device can be almost completely converted into an axially frozen mode characterized by a significantly increased amplitude, decreased group velocity normal to the incident surface and increased energy flux substantially tangential to the incident surface. The photonic device can be used in numerous applications over a wide range of frequencies up to and including the ultraviolet spectrum. The photonic device can be further configured with a deflection device which substantially increases the operational frequency range of the photonic device.
