Abstract

A novel and simple in-line fiber polarizer is presented. The proposed device is fabricated by tapering an anisotropic flat-cladding birefringent micro-fiber surrounding with low-dispersion optical-liquid cladding. We also presented a theoretical analysis for dispersive birefringence of flat-clad micro-fiber with liquid overlay. The proposed device can be useful as all-fiber polarizer for optical communications. Simulation results show the birefringence of the device can be enhanced when the aspect is larger. In the experimental measurement for polarization extinction ratio (PER) of the proposed device, a fiber-pigtailed 1549.25 nm DFB laser light was used as light source. The PER about 30 dB was demonstrated when the liquid with refractive index nD = 1.45 was used.
