| description | PURPOSE:To provide a high frequency resolution to cover a wide wavelength range by providing a resonator which has transmission characteristics by positions of plural frequencies whose intervals are different from those of frequencies of plural transmission light. CONSTITUTION:A frequency selecting means which detects the light having a desired frequency from transmission light having plural frequencies is provided with a Fabry-Perot laser 3 which has oscillation characteristics in positions of plural frequencies whose intervals are different from those of frequencies of plural transmission light and a control means which controls this resonator to select the light having a desired frequency. It is preferable that a Fabry-Perot etalon resonator where the resonator length can be controlled spatially or by the change of the refractive index or a resonator where the equivalent resonator length can be controlled is used as this resonator. Thus, a wide wavelength range is covered for frequency multiplex optical communication. |
