Abstract
In an optical circuit including multi-dimensional photonic crystals, in which the optical circuit has a structure (), such as a light emitting member or a light receiving member, having a natural resonance frequency, another structure () having a natural resonance frequency slightly differing from the natural resonance frequency of the structure () is arranged in the vicinity of the structure () to control the directivity of localization and propagation of an electromagnetic field, light emission and light reception in a spatial region including the above structures in the multi-dimensional photonic crystals, in order to permit functional operations to be realized.
