<p>PROBLEM TO BE SOLVED: To provide a thermally stabilized resonant electro-optic modulator which allows controlling a thermal stabilization unit on the basis of an output and an original input of the modulator which is not so complicated.SOLUTION: A thermally stabilized resonant electro-optic modulator 1 comprises: a resonant electro-optic modulator unit 2, the resonant electro-optic modulator unit comprising a first ring-shaped waveguide 3 and a second longitudinal waveguide 4 adjacent to the first waveguide; a voltage unit 5 for applying a first and a second voltage; a light sensor 6; a thermal stabilization unit 7; and a temperature control unit 8. The temperature control unit is provided for separately determining first intensity and second intensity, which are measured by the light sensor corresponding to the applied first voltage and the second voltage, at the first voltage and the second voltage respectively in function of time.</p> |
