An analysis of highly birefringence low losss index-guiding phptonic crystal fiber composed of different sized circular air-holes in cladding and adjacent to the two ellipital air-holes x-diraction in the first inner rings is carried out in this work using voul fector finite element method.The birefringence properities in terms of various parameters,e.g,pitch length,air-hole size and ellipticity ratio are calculated.Form the numerical results confirm that the size control of these air holes and pitch length is the key to reaching high model birefringnce.The proposed struture at wavelength 1.55μm shows a birefringence of up to 3.02x10^-2 and at the same time can get the confinement loss of less than 1.9x10^-7dB/m, which is a reference significance in useful to dessign temperature sensors.
