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 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. The results indicate that large attenuation can be achieved with a very small volume of PBG material. This will be of central importance in the design of the coming generation of PBG devices such as waveguides and filters.
