  • Patent number: 7194174
    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 ?. 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.

  • Publication number: 20040264903
    Abstract: An integrated photonic crystal (IPC) structure and method of producing same is disclosed. The (IPC) structure includes a first layered sub-structure (610, 620) with a surface and a one-dimensional periodic refractive index variation along the direction perpendicular to the surface. This first layered sub-structure enables a photonic band gap or high omnidirectional reflectivity for propagation of radiation having a spectrum of electromagnetic modes incident from a direction perpendicular to the plane of the surface. The PC-structure further includes a first defect (630) in the first layered sub-structure that enables an electromagnetic mode to be localised in the vicinity of the first defect. The electromagnetic radiation is hereby vertically confined. Furthermore, the IPC-structure consists of a second sub-structure with a plurality of essentially straight identical passages (635) arranged in a two-dimensional periodic pattern cutting through the layered structure at an angle &agr;.
