Abstract
A novel compact and multiband polarization beam splitter based on a dual-core transversally chirped microstructured optical fiber is proposed and analyzed, using finite element method. The results show that the ≈2.9 mm-long polarization splitter can reach an extinction ratio lower than -20 dB in two bands at 1140 nm and 1556 nm. The bandwidths of both bands are 11.7 nm and 47.2 nm respectively. This work analyzes the operation of the device when it is subjected to curvature, finding that it is possible to tune the operating bands. Numerical calculation indicates that this novel structure may find application in telecommunications, because it is capable of working at different wavelength ranges.
