ABSTRACT:
A frequency selective optical polarizer is formed by pressing a length of single mode polarization maintaining fiber 12 against a ribbed plate 10 in order to generate a distributed strain pattern with a periodicity which causes for a particular optical frequency one of the guided modes to couple into an unguided mode while the other guided mode remains substantially uncoupled.
