摘要: We propose a method for producing conical beam based on the lateral refraction of TM01 mode from two-mode fiber after chemical etching cladding, and controlling its radial polarization. The whole power guided is transferred to refracted with low diffraction. Polarization control by series azimuthal detectors stress controller affords transmission stabilized polarization through an optical fiber. A solid component usable many applications has been obtained.
