Abstract
An optical isolator for optically isolating an optical system, the optical system outputting electromagnetic radiation at predetermined ranges of frequencies, the optical isolator including a filter, and a Raman shifter, the filter is optically coupled with the output of the optical system and allows electromagnetic radiation of at least the predetermined ranges of frequencies to pass therethrough, the Raman shifter is optically coupled with the output of the filter for shifting the frequencies of the electromagnetic radiation through Raman scattering, the filter filtering back reflected portions of the shifted frequencies electromagnetic radiation.
