Claim Text:
1. An optical unit comprising: an input/output unit; a signal processing element modulating a beam input from the input/output unit; an optical system optically coupling the input/output unit and the signal processing element; an optical substrate mounting the input/output unit, the optical system, and the signal processing element; and a temperature controller controlling a temperature of the signal processing element, wherein the signal processing element includes an incidence surface on which the beam input from the input/output unit is incident, a modulation layer modulating the beam incident from the incidence surface, and a driving substrate for controlling the modulation of the beam arranged on the opposite side of the incidence surface in the modulation layer, 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 the second connection portion thermally connects the driving substrate and the temperature controller so that an area on the temperature controller side of the second connection portion to be more greatly deformed than an area on the driving substrate side of the second connection portion according to change in volume of the temperature controller.
