Paper Abstract

A strongly anisotropic photonic crystal structure was made exploiting form birefringence. It was designed to have a low group velocity close to a degenerate band edge (DBE) which is also associated with large field enhancements proportional to the fourth power of the number of periods. Numerical results are presented illustrating the expected properties and these are compared with experimental data. There are interesting discrepancies in behavior and possible reasons are discussed which include the nature of the anisotropy and fabrication-related structural disorder. At microwave frequencies, unexpected field enhancements at specific frequencies and locations outside the structure have been observed which have potential applications
