Photonic crystal device having variable bandgap, optical waveguide using the same, and optical multiplexing/demultiplexing device using the same |
摘要 |
A photonic crystal device having a variable bandgap includes a periodic structural body including a plurality of separate dielectric members arranged at intervals. The dielectric members are formed of a high-dielectric material. A variable-dielectric-constant material whose dielectric constant is varied by an electric field is filled in the spaces between the dielectric members. Electrodes are also provided for applying an electric field to the variable-dielectric-constant material.
