Abstract

LA INVENCION SE REFIERE A UN INTERFEROMETRO MACH-ZEHNDER OPTICO INTEGRADO CON DOS BRAZOS (11,12) CON LONGITUD DE PISTA GEOMETRICA DIFERENTE, DONDE UN PRIMER BRAZO (11) SE COMPONE DE PIEZAS (113, 114, 115, 116) DE ARCO Y PIEZAS (111, 112, 118) RECTAS, Y EL SEGUNDO BRAZO (12) CON REFERENCIA A LAS PIEZAS DE ARCO DEL PRIMER BRAZO (11) CONTIENE UNA PIEZA (123, 124, 125, 126) DE ARCO EN FORMACION SIMETRICA Y LA LONGITUD COMPLETA DE LAS PIEZAS (121, 127) RECTAS DEL SEGUNDO BRAZO (12) SON MENORES QUE LA LONGITUD COMPLETA DE LAS PIEZAS RECTAS DEL PRIMER BRAZO (11). CON EL ACOPLADOR 2 X 2 EN LA SALIDA COMO DEMULTIPLEXADOR PUEDE SER UTILIZADO EN LA VIA DE RADIACION INVERSA COMO MULTIPLEXADOR. LA DIFERENCIA DE FASE DE AMBOS BRAZOS ES LA DIFERENCIA DE LA LONGITUD DE CAMINO GEOMETRICA PROPORCIONALMENTE DIRECTA.
