Abstract

Ved en digital optisk bryter som er basert på prinsip-pet for modus-selektivitet, utgjøres denne av en passiv seksjon (A) inneholdende en første optisk bølgeleder (1) og en andre optisk bølgeleder (2), samt en svitsjeseksjon (B) som inneholder en tredje optisk bølgeleder (3) og en fjerde optisk bølgeleder (4), idet både den nødvendige asymmetri og fremskaffelsen av de optiske bølgeledere innenfor eller utenfor deres påvirkningsområde oppnås ved hjelp av kurver (K( K) i nevnte optiske bølgeledere. I svitsjeseksjonen (B) er nevnte asymmetri svitsjbar. Det gjøres bruk av det forhold at en kurve generelt resulterer i en reduskjon av utbredelseskonstanten i den optiske bølgeleder. Passende kurver har en sirkelbuet form eller sinusform. Svitsjeseksjonen (B) kan ytterligere innbefatte en kort mellomliggende seksjon (s-u) hvor de optiske bølge-ledere (12, 13) forløper rett under en liten innbyrdes vinkel (cp) i det tilfelle at den svitsjbare asymmetri i det første tilfelle er altfor liten med et spesielt materialvalg. Oppfinnelsen muliggjør meget kortere brytere som har en større pakketetthet.
