Abstract

Det er vist artikler og frem-gangsmåter for bølgelengdeomforming hvor. det benyttes en rekke innrettede avsnitt. (24, 25, 26, 27, 28) av optiske materialer for bølgelengdeomforming som er. valgt fra materialer med formelen. K.RbTiOM0, hvor x er fra 0 til 1 og M. er valgt fra P og As, og materialer med. den nevnte formel hvor kationene i formelen er blitt delvis erstattet av minst. én av Rb, Tlog Cs, og minst én av. Ba, Srog Ca. Rekken av avsnitt. karakteriseres med hensyn til en endring. i ikke-lineær, optisk koeffisient, av-snittslengde og Ak-verdi for avsnittene. (dvs. forskjellen mellom summen av for-plantningskonstantene for de innfallende. bølger og summen av forplantningskon-stantene for de frembrakte bølger).Avsnittene (24-28) er valgt slik at. summen for rekken av avsnitt av produk-tet av lengden av hvert avsnitt og Ak er. lik omtrent 2nN (hvor N er et helt tall. forskjellig fra null), og den ikke-lineære, optiske koeffisient for minst ett. avsnitt er endret i forhold til den ikke-lineære, optiske koeffisient for minst ett tilstøtende avsnitt. Det er også vist en fremgangsmåte for fremstil-ling av en kanalbølgeleder for bølge-lengdeomf ormingssystemer hvor områder langs et parti av en krystallsubstrat-overflate som benyttes for forming av den ønskede kanal, er vekselvis maskert og umaskert under kationutskiftning ved nedsenkning i et smeltet salt.
