Abstract

En hydrogenresistent fiber spesielt egnet for nedihullsapplikasjoner som omfatter en relativt tykk ren silikakjerne og et senket indekskappelag. Anbrakt mellom det senkede indeks-kappelaget og kjernen er et relativt tynt lag germaniumdopet grensesnitt. Ved å opprettholde et egnet forhold mellom den rene silikakjerne- diameteren og tykkelsen for det germaniumdopede grensesnitt vil en hoveddel (fordelaktig, mer enn 65%) av de forplantede signaler bli holdt innenfor den ene silikakjerne og derfor bli beskyttet fra hydrogeninduserte dempningsproblemer assosiert med nærvær av germanium (som er vanlig innenfor nedihulls- filterapplikasjoner). Den hydrogenresistente fiber ifølge den foreliggende oppfinnelse kan bli dannet for å inkludere en eller flere Bragg-gitre innenfor det germaniumdopede grensesnitt, noe som er anvendelig for avfølingsoppgaver.
