Abstract
A signal processing element that modulates beam from an input/output unit, an optical substrate mounting the signal processing element, and a temperature controller that controls a temperature of the signal processing element are included, the signal processing element includes an incidence surface on which the beam is incident, a modulation layer that modulates the beam from the incidence surface, and a driving substrate for controlling the modulation of the beam arranged on the opposite side of the incidence surface, the temperature controller is arranged opposite the driving substrate, the incidence surface is connected to the optical substrate by a first connection portion, the driving substrate is connected to the temperature controller by a second connection portion, and an area on the temperature controller side of the second connection portion is more greatly deformed than that on the driving substrate side according to change in volume of the temperature controller.
