The invention relates to an optical emission device comprising an integrated component consisting of a laser section (1) equipped with an oscillator section designed to supply a laser wave and a modulator section (2). To control the optical frequency of the modulated wave emitted, an electronic circuit (5, 6, 7, 11) controls the current (I1) from the laser section (1) in response to a measurement (V DC1) of the amplitude of modulation of the voltage induced at the terminals of the laser section by the modulator section (2).
L'invention se rapporte à un dispositif d'émission optique comprenant un composant intégré comportant une section laser (1) munie d'une section oscillateur prévue pour fournir une onde laser et une section de modulation (2). Afin de contrôler la fréquence optique de l'onde modulée émise, un circuit électronique (5, 6, 7, 11) commande le courant (I1) de la section laser (1) en réponse à une mesure (V DC1) de l'amplitude de modulation de la tension induite aux bornes de la section laser par la section de modulation (2).
