An optical device utilizes a polariton substance and utilizes the absorption wavelength band of excitonic polaritons. Further, an external stimulus such as electric field, magnetic field, stress, current or electromagnetic wave (light) is continuously or intermittently given to the polariton substance, thereby to modulate light which enters the optical device. Thus, a modulating operation of ultra-high speed is possible.
