Abstract:
(EN) A right angle waveguide having a square rod-type square lattice photonic crystal and a single compensation scattering rod having a high refractive index. The right angle waveguide is a photonic crystal formed from first dielectric rods having a high refractive index arranged in a background dielectric having a low refractive index according to a square lattice. In the photonic crystal, one row and one column of the first dielectric rods having the high refractive index are removed to form the right angle waveguide. A second dielectric rod having a high refractive index is arranged at a corner of the right angle waveguide, the second dielectric rod being the compensation scattering rod. The first dielectric rods are square rods having the high refractive index. The right angle waveguide has extremely low reflectance and a very high transmission rate, and facilitates large-scale optical path integration.
(FR) L'invention concerne un guide d'ondes à angle droit qui comporte un cristal photonique à réseau orthogonal de tiges carrées et une tige unique de dispersion de compensation ayant un indice de réfraction élevé. Le guide d'ondes à angle droit est un cristal photonique qui est constitué de premières tiges diélectriques ayant un indice de réfraction élevé disposées dans un diélectrique d'arrière-plan ayant un faible indice de réfraction selon un réseau orthogonal. Dans le cristal photonique, une rangée et une colonne de premières tiges diélectriques ayant un indice de réfraction élevé sont retirées pour former le guide d'ondes à angle droit. Une seconde tige diélectrique ayant un indice de réfraction élevé est disposée à un coin du guide d'ondes à angle droit, la seconde tige diélectrique étant la tige de dispersion de compensation. Les premières tiges diélectriques sont des tiges carrées ayant un indice de réfraction élevé. Le guide d'ondes à angle droit présente un facteur de réflexion extrêmement faible et une vitesse de transmission très élevée, et il facilite l'intégration à grande échelle de chemins optiques.
(ZH) 一种方柱式正方晶格光子晶体高折射率双补偿散射柱直角波导,它是由高折射率的第一介质柱在低折射率背景介质中按正方晶格排列而成的光子晶体。在光子晶体中移除一排和一列高折射率的第一介质柱以形成直角波导。在直角波导的拐弯处设置一个高折射率的第二介质柱,第二质柱为补偿散射柱。第一介质柱为高折射率方柱。该直角波导具有极低的反射率和非常高的传输率,便于大规模光路集成。
