Abstract

EN CONOCIDOS RECEPTORES OPTICOS COHERENTES CON DOS DETECTORES, HIBRIDOS OPTICOS A 90 (GRADOS) TIENEN UN ''RENDIMIENTO'' (MENOR O IGUAL) 25 %. EL ANALISIS TEORICO REVELA QUE ES POSIBLE UN RENDIMIENTO MAYOR, HASTA UN MAXIMO DE APROXIMADAMENTE 29,3 %. LA INVENCION PROPONE UN HIBRIDO TAL A 90 (GRADOS) (30) DEL TIPO ACOPLADOR CON LA AYUDA DE UN PUERTO 2X2 EL CUAL ESTA BASADO EN UN ACOPLADOR DIRECCIONARL 3X3 EXENTO DE PERDIDA, QUE TIENE RELACIONES DE RENDIMIENTO MAXIMO ENTRE DOS DE LAS ENTRADAS (31/39, 32/40) Y DOS DE LAS SALIDAS (39/34, 40/35) Y LA DIFERENCIA DE FASE DE 90 (GRADOS) ENTRE DICHAS DOS SALIDAS, NO SIENDO USADAS LA TERCERA ENTRADA Y LA TERCERA SALIDA. SE DESCRIBE UNA VERSION INTEGRADA QUE EMPLEA FOSFURO DE INDIO.
