ABSTRACT:
An optical isolator, which has: a medium through which a light transmits and in which a dynamic diffraction grating that periodically repeats a refractive index distribution is formed; wherein the dynamic diffraction grating causes a propagation loss difference between an incident light which is supplied into the medium and a returning light which is supplied into the medium in a direction reverse to the incident light.
