ABSTRACT:
An optical attenuator has first and second lenses provided individually on the respective end faces of first and second optical fibers that are opposed to each other across a space, and a shutter plate interposed between the lenses. The distance between the shutter plate and the second lens and a mode-field radius of propagating light on the second-lens-side surface of the shutter plate are set so that the respective signs of the real and imaginary parts of an evaluation function, representing a diffraction pattern of the propagating light that propagates from the first optical fiber to the second optical fiber, are inverted 60 times or more when a variable of the evaluation function is changed within an evaluation range.
