摘要 |
<p>In a 2D photonic crystal waveguide comprising a 2D photonic crystal structure based on a slab (11) formed of a material having a higher refractive index than air, in which a material (16) having a lower refractive index than the slab material is periodically arrayed to provide a refractive index distribution, a photonic crystal waveguide is created by forming a line defect (12), which functions as a waveguide, in the periodic array of photonic crystal, and at least one point defect (14) is disposed adjacent the photonic crystal waveguide to act as a disorder in the periodic array of photonic crystal. The point defect functions as a light or electromagnetic radiation outlet/inlet port for trapping light or electromagnetic radiation of a selected wavelength among light or electromagnetic radiation propagating through the waveguide and radiating it in a direction orthogonal to the slab surface or trapping light or electromagnetic radiation of a selected wavelength from an exterior direction orthogonal to the slab surface and introducing it into the waveguide. &lt;IMAGE&gt;</p> |
