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 .alpha.. 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.
