Optics letters, 1996•opg.optica.orgWe propose the concept of a photonic band-gap (PBG) prism based on two-dimensional
PBG structures and realize it in the millimeter-wave spectral regime. We recognize the highly
nonlinear dispersion of PBG materials near Brillouin zone edges and utilize the dispersion
to achieve strong prism action. Such a PBG prism is very compact if operated in the optical
regime,~ 20 μm in size for λ~ 700 nm, and can serve as a dispersive element for building
ultracompact miniature spectrometers.
