an incoming signal into two orthogonal polarization states are analyzed by using finite
element method. The proposed splitter has a short length of 117 μm, being capable of
splitting an incoming wave into two orthogonal states in the wavelength range between
1250 and 1710 nm. The main properties of the splitter are calculated such as extinction ratio,
bandwidth, dispersion, mode-field-diameter and splice loss—the device would have a mode …
