| titleOfInvention | Photonic crystal waveguide, homogeneous media waveguide, and optical element |
| abstract | PROBLEM TO BE SOLVED: To provide a photonic crystal waveguide, a homogeneous medium waveguide, and an optical element using these, which can be arranged at an arbitrary angle and can be bent sharply and have low propagation loss. A photonic crystal waveguide 200 having a core made of a photonic crystal 50 having periodicity in the Y direction. The electromagnetic wave propagates through a band on the boundary line of the Brillouin zone in the photonic band structure of the core, the side surface parallel to the Y direction of the core is in contact with a homogeneous medium having a refractive index n s , and the wavelength of the electromagnetic wave in vacuum is λ 0 , The period of the photonic crystal is a , The period in the XZ plane direction of the wave propagating in the core is λ, satisfy the λ 0 / n s> aλ / (λ 2/4 + a 2) 0.5. This condition is the minimum necessary condition to prevent leakage light from being generated from the side surface of the photonic crystal waveguide 200. By satisfying this condition, the wave propagating in the core is the side surface when the propagation angle φ = 0 °. Can be confined. [Selection] FIG. 29 |
