Abstract:
1. An optical resonator comprising: a master resonator configured to resonate an electromagnetic wave; one structure or a pair of structures adjacent to each other, each of which is arranged at a position that overlaps one of resonance modes of the master resonator, the one structure or the pair of structures being made up of a material in which a real part of a permittivity assumes a negative value, and an absolute value of the real part is larger than an absolute value of an imaginary part of the permittivity, the one structure or the pair of structures having a size which makes scattering that the electromagnetic wave suffers be Rayleigh scattering; and one or a plurality of particles, each of which is laid out near the structure by a distance smaller than the size of the structure, wherein the structure has a shape which is not a perfect sphere, and the structure is laid out in a direction in which a direction of a maximum dimension of the structure agrees with directions of electric fields in the resonance modes or directions of electric fields in one or more of degenerate resonance modes.
