Abstract

Both patterned periodic or random structures can exhibit large slow down factors associated with large field enhancements. These properties can be exploited to good effect for a variety of sensing functions. We describe here some basic mechanisms responsible for these effects and discuss their use. Some experimental results are reported using porous form-birefringent super-lattice structures which can be scaled in size for use from microwave to optical frequencies.


Keywords: Periodic structures, field enhancement, slow light.
