Abstract
A light controlling means includes a shutter member and an actuator. The shutter member is disposed in a slit and has a function to shut off signal light propagated in the light path of an optical fiber array. The actuator is constructed to drive and move the shutter member in a vertical direction. The shutter member is fixed to one end of the actuator and positioned substantially in alignment with an inclination angle of the slit. Further, a base member of the shutter member is made from transparent quartz glass. A light reflecting film is formed on a portion of one of the plate surfaces of the shutter member, on a surface opposite the optical axis of a light exit portion.
