Abstract


Proponemos un nuevo oscilador optoelectrónico basado en la dispersión estimulada de Brillouin para generar una portadora de microondas, ultra estrecha y estable, como lo muestra su bajo ruido de fase. Un láser de Brillouin sub-kHz de anillo de fibra con estabilización activa y encadenamiento por inyección a su bombeo DFB (del inglés, Distributed Feedback Laser) se propone como técnica básica para la generación de microondas. El oscilador optoelectrónico genera una señal portadora de ~10.946 GHz, con un ancho de banda de 300 Hz a 3 dB. Las señales armónicas parasitas están a ±50 kHz, ±450 kHz and ±900 kHz, con un nivel de 45-50 dB desde el pico de la portadora. El ruido de fase está por debajo de -90 dBc/Hz a un desplazamiento de frecuencia de la portadora de 10 kHz, este nivel se observa en una trasmisión de prueba a través de una fibra óptica de 20 Km de longitud

Keywords
