Two-dimensional photonic crystal slab, two-dimensional photonic crystal waveguide and optical device |
摘要 |
<p>A two-dimensional photonic crystal slab having a photonic band gap common to a light beam in the TE-like mode and a light beam in the TM-like mode includes a slab member containing a high refractive index material and low refractive index sectors, arranged in the slab member in a triangular pattern, having a triangular prism shape. The two-dimensional photonic crystal slab further includes a linear defect section that is a disordered portion in a periodic structure of a photonic crystal and extends in the GAMMA -J direction. Light beams in the TE-like mode and light beams in the TM-like mode can be propagated through the waveguide section. <IMAGE></p> |
