Optical preamplifier device for photodetector comprising a first optical amplifier (10). The said first optical preamplifier (10) is coupled to an input of an optical filter (30) centred on a fixed wavelength 10 via a wavelength conversion device (20) to the fixed wavelength 10 of the filter, making the device independent of the wavelength 1i of the signal.

Dispositif préamplificateur optique pour photorécepteur comportant un premier amplificateur optique (10). Ce premier amplificateur optique (10) est couplé à une entrée d'un filtre optique (30) centré autour d'une longueur d'onde fixe l0 à travers un dispositif à conversion de longueur d'onde (20) à la longueur d'onde l0 fixe du filtre, permettant ainsi de rendre le dispositif indépendant de la longueur d'onde l i du signal.
