Abstract

EN LA TRANSMISION DE SEÑALES DE ALTA FRECUENCIA DE SUCESION DE BIT A TRAVES DE TRAMOS DE TRANSMISION A DISTANCIA ES NECESARIO EL PUNTO CERO DE DISPERSION {LA}0, PARA GARANTIZAR UNA TRANSMISION VIABLE. LA INVENCION UTILIZA DE FORMA CONOCIDA UN EFECTO PERTURBADOR, NO DESEADO EN LA TECNICA DE TRANSMISION DE MENSAJES OPTICOS, QUE REDUCE LA CALIDAD DE TRANSMISION. ESTE EFECTO ES LA MEZCLA DE CUATRO ONDAS CONOCIDAS O EN CASOS ESPECIALES LA MEZCLA DE CUATRO ONDAS DEGENERADAS PARCIALMENTE. EN EL PROCEDIMIENTO DE ACUERDO CON LA INVENCION SE ACOPLAN DOS SEÑALES DE LUZ DE LONGITUD DE ONDA {LA}1, {LA}2 DIFERENTE EN UN CONDUCTOR (4) DE ONDA DE LUZ. EN EL CONDUCTOR DE ONDA DE LUZ COMO CONSECUENCIA DE UNA MEZCLA DE CUATRO ONDAS DEGENERADAS PARCIALMENTE APARECE UN PRODUCTO DE MEZCLA QUE SE VALORA EN UN ANALIZADOR (3). LAS LONGITUDES DE ONDA DE UNA DE AMBAS SEÑALES DE LUZ SE MODIFICA DE FORMA TAN AMPLIA, QUE SE HACE MAXIMA LA POTENCIA OPTIMA DEL PRODUCTO DE MEZCLA. CON ELLO SE SOLAPA LA LONGITUD DE ONDA DEESTA SEÑAL DE LUZ CON EL PUNTO CERO DE DISPERSION {LA}0.
