Abstract
A light operation device includes: an light input and output port; an light-operating element reflecting a light input from any one of the ports of the light input and output port and outputting the reflected light to any one of the ports of the light input and output port; a condensing lens system disposed between the light input and output port and the light-operating element and optically-coupling the light input and output port with the light-operating element; an anamorphic optical system disposed between the light input and output port and the condensing lens system and expanding a beam diameter of the light input from a side of the light input and output port in a beam-diameter-expanding direction. In the condensing lens system, a first focal distance in the beam-diameter-expanding direction and a second focal distance in a direction perpendicular to the beam-diameter-expanding direction differ from each other.
