Abstract
The invention relates to a light emitter device comprising an integrated component having a laser section provided with an oscillator section designed to supply a laser wave, and a modulator section. In order to control the light frequency of the emitted modulated wave, an electronic circuit controls the current of the laser section in response to a measurement of the amplitude of the modulation of the voltage induced across the terminals of the laser section by the modulation section.
