Abstract

EMISOR LASER (LS) CON LASER SEMICONDUCTOR (HL) Y RESONADOR (ER) EN FORMA DE ACOPLAMIENTO DE AJUSTE OPTICO (RK) Y CON UN CONDUCTOR DE ONDAS (WL1) DEL ACOPLAMIENTO DE AJUSTE (RK) CON DISPOSITIVO DE REACOPLAMIENTO (RKE1) PARA REACOPLAR UNA PARTE DEL RENDIMIENTO DE RADIACION QUE PASA POR ESTE CONDUCTOR DE ONDAS (WL1) HACIA EL ACOPLAMIENTO DE AJUSTE (RK), PUDIENDOSE TOMAR EL RENDIMIENTO DE SALIDA (AST) DEL EMISOR (LS) DEL OTRO CONDUCTOR DE ONDAS (WL2) DEL ACOPLAMIENTO DE AJUSTE (RK). UN EMISOR YA PROPUESTO QUE TRABAJA CON UN CONDUCTOR DE ONDAS DE BUCLE. PARA ELLO SE PREVEE OTRO CONDUCTOR DE ONDAS (WL2) CON SU DISPOSITIVO DE REACOPLAMIENTO (RKE2), QUE TIENE LA MISION DE QUE POR LO MENOS UNA PARTE DEL RENDIMIENTO DE RADIACION TRANSPORTADO AL OTRO CONDUCTOR DE ONDAS (WL2) PASE DE NUEVO AL ACOPLAMIENTO DE AJUSTE (RK), PREFIRIENDO DISTANCIAS OPTICAS (L1,L2) ENTRE EL ACOPLAMIENTO DEL AJUSTE (RK) Y UNO DE LOS DISPOSITIVOS DE REACOPLAMIENTO (RKE1) U OTRO (RKE2) QUE SEAN DIFERENTES ENTRE SI POR UN DETERMINADO NUMERO. EL EMISOR PUEDE SER DE EJECUCION OPTICA INTEGRADA.
