Abstract
The present invention describes the use of photonic crystals to form optical elements which function in optical apparatus in frequency ranges outside photonic band-gaps. Such optical elements may apply such optical properties as dispersion, anisotropy, and birefringence (all of which are exhibited by photonic crystals outside photonic band-gaps). A variety of optical apparatus, including spectrometers, radiation sources, and lasers are enabled by such optical elements.
