Tapered optical fiber, Whispering gallery mode, PolarizationAbstract
Tapered optical fiber evanescent light wave polarization control is demonstrated with the utilization of free-space optics polarization resolved set-up. TE- and TM-polarised lasing light discrimination of > 20 dB could be achieved with the proposed setup and with tapered optical fiber of 2 μm waist diameter. Investigation on the performance of the proposed tapered optical fiber with whispering gallery mode (WGM) optical microresonators show distinguishable TE and TM group-mode families with high Q-factor and sharp wavelength dip contrast.
