Abstract[English]
The present disclosure relates to a monolithically integrated dual-wavelength transmitter for a passive optical network (PON), which may be suitable for both a gigabit PON (GPON) and a 10-gigabit-PON (XG-PON). The integrated transmitter includes two distributed feedback (DFB) lasers, a first DFB laser to emit a continuous first laser beam at a first wavelength along an optical path, and a second DFB laser to emit a modulated second laser beam at a second wavelength along the optical path in the same direction as the first DFB laser. The transmitter also includes an electro-absorption modulator (EAM) after the first DFB laser in the optical path, which is configured to modulate the first laser beam, and a distributed Bragg reflector (DBR) between the EAM and the second DFB laser in the optical path, which is configured to transmit light at the first wavelength[French]
La présente divulgation concerne un émetteur à double longueur d'onde intégré de façon monolithique pour un réseau optique passif (PON), qui peut être approprié à la fois pour un PON gigabit (GPON) et un PON 10-gigabits (XG-PON). L'émetteur intégré comprend deux lasers à rétroaction répartie (DFB), un premier laser DFB servant à émettre un premier faisceau laser continu à une première longueur d'onde le long d'un chemin optique, et un second laser DFB servant à émettre un second faisceau laser modulé à une seconde longueur d'onde le long du chemin optique dans la même direction que le premier laser DFB. L'émetteur comprend également un modulateur d'électro-absorption (EAM) après le premier laser DFB dans le chemin optique, qui est configuré pour moduler le premier faisceau laser, et un réflecteur de Bragg réparti (DBR) entre l'EAM et le second laser DFB dans le chemin optique, qui est configuré pour transmettre de la lumière à la première longueur d'onde.
