| 摘要 |
A photonic crystal-based resonant cavity includes a first dielectric substance (110) having a first dielectric permittivity, a plurality of second dielectric substances (120) having a second dielectric permittivity and arranged in a first periodic structure with respect to at least one or more directions on a plane formed of the first dielectric substance (110), a plurality of third dielectric substances (130) having a third dielectric permittivity and arranged in a second periodic structure with respect to at least one or more directions on the plane formed of the first dielectric substance (110), and disposed in unit cells formed by the plurality of second dielectric substances (120) so as to be arranged in a third periodic structure together with the plurality of second dielectric substances, and one or more local defects (140) formed to disrupt either the first periodic structure formed by the second dielectric substances or the second periodic structure formed by the third dielectric substances. <IMAGE> |
