摘要： At least one exemplary embodiment is directed to a waveguide, which includes a three-dimensional photonic crystal including a first linear defect and a second linear defect. The first linear defect is disposed at part of columnar structures and is formed of a medium different from the columnar structures. The second linear defect is disposed at part of columnar structures extending in the longitudinal direction of the first linear defect and is formed of a medium having a refractive index different from that of the medium used for the columnar structures. The second linear defect is separated from the first linear defect by a distance of at least 0.5 times the out-of-plane lattice period of the three-dimensional photonic crystal in a direction in which layers including the columnar structures are stacked.

摘要： The three-dimensional structure includes a first waveguide (line defect) in a three-dimensional photonic crystal formed by periodically arranging first and second media, which causes light to propagate therein in a first guide mode, a second waveguide (line defect) in the three-dimensional photonic crystal, which causes light to propagate therein in a second guide mode, reflective portions provided in the first and second waveguides to reflect parts of the lights propagating in the first and second waveguides, and a first region connected to the second waveguide so as to cause at least part of the light that has propagated in the second waveguide via the reflective portion to propagate therein in a third guide mode. The reflective portions are formed of media having refractive indexes different from those the first and second waveguides. Each reflective portion has a homogeneous refractive index distribution in an entire section orthogonal to a waveguide-extending direction.
