<p>Thermally stabilised resonant electro-optic modulator (1) comprising a silicon ring resonator (3) and two straight waveguides (4, 9) coupled to it, wherein the modulator (1) further comprises a voltage unit (5) arranged to receive a data stream and to apply first and a second voltages, respectively corresponding to logic zeros and logic ones in the data stream, to the ring resonator (3), the modulator further including a light sensor (6) arranged to separately sample in time first and second intensities of light transmitted through the waveguide (4) upon application of the first and second voltages, as well as to provide the separately sampled intensities to a temperature control unit (8), this unit being arranged to control a thermal stabilisation unit (7) on the basis of the sampled intensities.</p> |
