Abstract :
Summary form only given. Although it is well known that photonic band gap (PBG) materials can provide a high degree of attenuation within the photonic band gap, relatively little work has been done on visible or near-infrared gap materials to investigate exactly how this attenuation depends on the material thickness. This is an important issue because it is the attenuating property of photonic band gap materials that makes them so attractive as photonic circuit elements. We report on the band-gap transmission properties of a 2D silicon PBG materials as a function of material thickness and wavelength with transmissivity as low as 3/spl times/10/sup -4/ being observed for only 4 unit cell thickness.
