We numerically analyze a polarization maintaining (PM) supercontinuum generation (SCG) in all-normal dispersion liquid (CS 2 )-core photonic crystal fiber (LC-PCF). The proposed LC-PCF affords a high birefringence (10 &#x2212;3  to 10 &#x2212;2 ) from 1.0 &#x03BC;m to 2.2 &#x03BC;m wavelength with fundamental mode behavior. The linear polarization and high coherence spectral width for X and Y polarized axes covers 1.32 &#x03BC;m&#x223C;2.28 and 1.28 &#x03BC;m&#x223C;2.24 &#x03BC;m with pump wavelength of 1.55 &#x03BC;m at pump power of 2 kW, respectively. Furthermore, we found that the ability of maintaining linear polarization state of SC source for X-axes is better than that of Y-axes as the pulse duration varies from 0.05 ps to 0.6 ps at the same pump wavelength. In addition, the proposed LC-PCF-based SC source is a good candidate for applications such as biomedical imaging, fluorescence lifetime imaging fields, and frequency comb sources.
