Optical effects in photonic crystals and metamaterials

In this thesis, I will describe the polarization properties of two separate
but similar optical systems. I will begin by showing anisotropy in a
dielectric photonic crystal slab patterned with a periodic circular hole array.
This anisotropy can be utilized in manipulating the gain properties of surface
emitting photonic crystal lasers. I will then describe a metallic, planar metamaterial
patterned similarly with a 2d periodic array of holes. The enhanced
optical transmission of this system is demonstrated computationally and experimentally,
with a good agreement between the two. I will also demonstrate
polarization rotation in this array. The effect is shown to minimize the background
contribution to the transmission resulting in the narrowing of the line
width and improvement between on and off resonance contrast. I then provide
a theory behind the polarization rotation in transmission through a metamaterial
based upon a Jones matrix formulation, which is dependent only upon
the existence of separate s and p resonances in a photonic system. / text
