Abstract
PROCEDIMIENTO PARA LA FABRICACION DE GUIAS DE ONDA PARA EL INDICE DE REFRACCION ORDINARIO DEL NIOBATO DE LITIO MEDIANTE DOBLE INTERCAMBIO IONICO. CON UN PRIMER INTERCAMBIO PROTONICO PROFUNDO SE GENERA UNA CAPA DE VARIAS MICRAS DE ESPESOR DE LA CUAL SE HA EXTRAIDO UNA CIERTA FRACCION DE LOS IONES LITIO DEL MATERIAL, GENERANDO UNA DISMINUCION DEL INDICE ORDINARIO EN APROXIMADAMENTE DLNO _ 0,04 (FIG. 1). CON UN SEGUNDO INTERCAMBIO MENOS PROFUNDO QUE EL PRIMERO, EN SOLUCION RICA EN LITIO, SE REINTRODUCEN LOS IONES DE LITIO Y SE RECUPERA EL INDICE ORDINARIO APROXIMADAMENTE A SU VALOR INICIAL, EN UNA CAPA MENOR QUE LA PRIMERA. ESTA ULTIMA CAPA JUNTO CON EL RESTO DE LA CAPA ANTERIOR QUE HACE DE SUSTRATO EFECTIVO CONSTITUYE LA GUIA DE ONDAS (FIG. 2). LA GUIA DE ONDAS FINALMENTE TIENE UN SALTO DE INDICE ORDINARIO DE DLNO 0,03 PARA LA = 0,6328 MIM.PROCEDURE FOR THE MANUFACTURE OF WAVE GUIDES FOR THE REGULAR REFRACTION INDEX OF LITHIUM NIOBATE THROUGH DOUBLE ION EXCHANGE. WITH A FIRST DEEP PROTONIC EXCHANGE A LAYER OF SEVERAL MICRONS THICKNESS IS GENERATED FROM WHICH A CERTAIN FRACTION OF THE LITHIUM IONS OF THE MATERIAL HAS BEEN REMOVED, GENERATING A DECREASE IN THE REGULAR INDEX IN APPROXIMATELY DLNO _ 0.04 (FIG. 1). WITH A SECOND EXCHANGE LESS DEEP THAN THE FIRST, IN A LITHIUM-RICH SOLUTION, THE LITHIUM IONS ARE REINTRODUCED AND THE REGULAR RATE IS RECOVERED APPROXIMATELY AT ITS INITIAL VALUE, IN A LAYER LESS THAN THE FIRST. THIS LAST LAYER TOGETHER WITH THE REST OF THE PREVIOUS LAYER THAT MAKES AN EFFECTIVE SUBSTRATE CONSTITUTES THE WAVE GUIDE (FIG. 2). THE WAVE GUIDE FINALLY HAS A REGULAR INDEX JUMP OF DLNO 0.03 FOR THE = 0.6328 MIM.
