A kind of single-polarization and single-mode photonic crystal fiber (SPSM PCF) is proposed in this paper. It is a PCF structure with elliptical air holes in the cladding and four large holes introduced in the first ring. A full-vector plane wave expansion method is employed to analyze this PCF structure. The numerical results show that this PCF structure can realize ultra-broad SPSM bandwidth as 540nm with the confinement loss less than 0.1dB/km, the broadest bandwidth as far as our knowledge goes.
