Abstract

En optisk fiber (40) omfatter en bølgeleder (41) omgitt av en omhylning (42) og en beskyttende kappe (43). Bølgelederen (41)s brytningsegenskaper kan endres i respons til elektromagnetisk energi. I den ytre overflate av fiberens (40) er dannet tninst ett spor (46) som utstrekker seg langs en valgt lengde av fiberen (40) for å motta en elektrode som kan pålegge en elektrisk spenning som resulterer i en endring av brytningsegenskapene for bølgelederen (41) .
