    • An optical element, optical control device and optical control method are provided which demonstrate a large, rapid optical response using a laser light of low output as a control light. A signal light 1 is emitted from an optical source 1. A signal light 2 emitted from an optical source 2. A control light and the signal light are converged by a condenser lens 7, and irradiate an optical element 8. Only the signal light is detected by a photodetector 22 through a light receiving lens 9 and a wavelength selection filter 20. A thermal lens is formed reversibly in the optical element and switching the control light ON and OFF modulates the intensity of the signal light. The optical element has a laminar structure comprising a heat transfer film/heat insulation film/light absorption film/heat insulation film/heat transfer film, for example, and a sufficiently large and rapid optical response is obtained using low output laser light as the control light by adjusting the thickness of the light absorption film so that it does not exceed twice the confocal length of the converged control light.
