Polarization beam splitters (PBSs) are a special kind of coupler. They can split incoming light from a single fiber into two orthogonally polarized beams. They are usually used in coherent optical communication systems, optical sense systems and optical measurement systems. In this paper, two kinds of mechanisms of the PBSs based on photonic crystal fibers (PCFs) are discussed. The full-vector finite...
A temperature sensor based on fibers Bragg grating in photonic crystal fibers is simulated. Fibers Bragg grating has been widely used in the field of sensor. The temperature property of uniform fibers Bragg grating in photonic crystal fibers was studied. By finite element method, the relation between the birefringence in photonic crystal fibers and the temperature was analyzed. Numerical results show...
