Optical element using one-dimensional photonic crystal and spectroscopic device using the same |
摘要 |
An optical element using one-dimensional photonic crystal according to the invention includes a multilayer film, which is achieved by an element processed into a triangular prism shape. A phase modulation unit is provided so as to be adjacent or abutting to a light input end surface of the optical element. Input light is phase-modulated by the phase modulation unit in the same period and direction as those of photonic crystal so that only specific high-order band light can be propagated through the optical element. When this optical element is formed in an optical waveguide, a small-size spectroscopic device having high resolving power can be provided.
