Abstract
An integrated photonic crystal (IPC) structure and method of producing the same in which the IPC structure includes a first layered sub-structure with a surface and a one-dimensional periodic refractive index variation along the direction perpendicular to the surface, and a second sub-structure with a plurality of essentially straight identical passages arranged in a two-dimensional periodic pattern cutting through the layered structure at an angle α. First and second defects in the first and second sub-structures, respectively, enable electromagnetic modes to be localized in the vicinity of the defects and allow photonic crystal waveguide to be constructed that can control and filter light very efficiently and minimize radiation losses.
