ABSTRACT:
There is provided an attenuator device having a simple configuration and capable of selecting an output of beam of an arbitrary wavelength range from a plurality of output ports. The attenuator device comprises: a plurality of output fibers (1-3and1-5) having an end surface serving as an output port; discarding optical fibers (1-2and1-4) having an end surface serving as a discarding port and each arranged adjacently to the output optical fiber; a diffraction grating (5) which diffracts an incident beam into various directions according to the wavelength thereof; and a micro mirror array (7) which adjusts the output direction of the diffracted beam for each of the wavelength ranges output from the diffraction grating (5). The micro mirror array (7) adjusts the output direction of the diffracted beam so that a part of the diffracted beam may be output to the output port while the rest being output to the discarding port.
