ABSTRACT:
An optical system111collimates wavelength components of wavelengths λ1-λ3emerging from an end face of optical fiber11, a diffraction grating121separates them by wavelength, and an optical system112condenses them. The component of the wavelength λ1is focused at a focus position by the optical system112and diverges after the focus position. Then the component of the wavelength λ1is collimated by an optical system113, travels via a diffraction grating122, and is condensed by an optical system114to enter an end face of optical fiber22. The component of the wavelengths λ2, λ3condensed by the optical system112are reflected by reflecting portions132, 133set at their respective focus positions, are collimated by the optical system112, travel via the diffraction grating121, and are condensed by the optical system111to enter an end face of optical fiber.
