PHOTONIC CRYSTAL AND OPTICAL FUNCTIONAL DEVICE INCLUDING THE SAME

摘要

An object to provide a photonic crystal capable of resonating light at more resonant frequencies within a particular frequency range. A plurality of photonic crystal structure formation bodies each including a plate-like member in which cyclic refractive index distribution is formed are provided so as to be spaced apart from each other in the thickness direction of the plate-like member, and the respective refractive index distributions of the plurality of photonic crystal structure formation bodies are set such that: at least one of the plurality of photonic crystal structure formation bodies resonates with light having at least two frequencies within the frequency range; and the two frequencies are different from resonant frequencies of at least one of the other photonic crystal structure formation bodies.

1. A photonic crystal that resonates with light having a plurality of frequencies within a predetermined frequency range, comprising:
a plurality of photonic crystal structure formation bodies each including a plate-like member in which cyclic refractive index distribution is formed, the photonic crystal structure formation bodies being provided so as to be spaced apart from each other in a thickness direction of the plate-like member, wherein the respective refractive index distributions of a first photonic crystal structure formation body that is one of the plurality of photonic crystal structure formation bodies and a second photonic crystal structure formation body that is one of the other photonic crystal structure formation bodies are set such that: the first photonic crystal structure formation body resonates with light having at leas two resonant frequencies within the frequency range; the two resonant frequencies are different from all resonant frequencies of the second photonic crystal structure formation body; and at least one of the resonant frequencies of the second photonic crystal structure formation body has a value between the two resonant frequencies.
