Abstract
EN UN DISPOSITIVO OPTICO PARA LA EXTRACCION DE LA SEÑAL DE RELOJ DE ALTA VELOCIDAD, UNA SEÑAL DIGITAL DE ENTRADA SE DIVIDE ENTRE DOS TRAYECTORIAS (11, 25). LA SEÑAL QUE SE ENCUENTRA EN UNA TRAYECTORIA (25) ES ALIMENTADA DIRECTAMENTE EN UN RECEPTOR (203), MIENTRAS QUE LA SEÑAL DE LA OTRA TRAYECTORIA (11) ES ALIMENTADA EN UN AMPLIFICADOR OPTICO NO LINEAL (1) QUE TIENE REGIONES DE GANANCIA Y DE ABSORCION INDEPENDIENTES. LA SEÑAL DE ENTRADA DISPARA EL AMPLIFICADOR OPTICO NO LINEAL (1) PARA PULSAR A UNA FRECUENCIA DE RELOJ QUE SE ENCUENTRA EN LA SEÑAL Y LA SEÑAL DE RELOJ DE SALIDA FUERTE RESULTANTE QUEDA ACOPLADA A LA TRAYECTORIA (25) QUE LLEVA LA SEÑAL DE ENTRADA AL RECEPTOR (203). EL AMPLIFICADOR OPTICO NO LINEAL (1) PUEDE PROPORCIONAR UNA SALIDA DE RELOJ DE MUY ALTA FRECUENCIA COMO RESULTADO DE LA MODIFICACION SELECTIVA DE LA DURACION DE LA PORTADORA.
