CA 2103859

An entry signal provided by a generator (3)) is applied to a laser emitting diode (10) through a pre-distortion circuit to ameliorate the linearity of the source's response. This circuit comprises a Pi linear attenuator unit made up of resistors (12, 13, 14, 15 and 16), and a non-linear compensating element made up of a Schottky diode (20) connected in parallel with the attenuator unit. The invention applies principally in the manufacture of optical heads for optical fibre telecommunications systems.

Un signal d'entrée fourni par un générateur (30) est appliqué à une diode émettrice laser (10) à travers un circuit de prédistorsion pour améliorer la linéarité de la réponse de la source. Ce circuit comporte un organe atténuateur linéaire en pi constitué par des résistances (12, 13, 14, 15 et 16), et un élément compensateur non linéaire constitué par une diode Schottky (20) connectée en parallèle avec cet organe atténuateur. L'invention s'applique notamment à la réalisation de têtes optiques pour les systèmes de télécommunication à fibres optiques.
