Abstract:
A chiral polarizer comprising:an elongated chiral optical fiber being of a predetermined handedness said chiral optical fiber having a core disposed along its longitudinal axis and a cladding surrounding said core, said chiral optical fiber having a first end and a second end, and having at least one predetermined pitch between said first and said second ends, wherein said at least one predetermined pitch is sufficiently short such that, when incident unpolarized light having a first circularly polarized component and a second circularly polarized component, enters said first end, said core scatters one of said first and second circularly polarized components that matches said predetermined handedness, and transmits the other circularly polarized component through said second end, thus polarizing said incident light into circularly polarized light having an opposite handedness to said predetermined handedness.
