Through introducing two sizes of hole in the cladding of PCF, a kind of highly birefringent two-mode photonic crystal fiber (PCF) is proposed. Modal properties are analyzed numerically by the plane wave expansion method. Numerical results demonstrate that only two-mode, i.e. LP01 and LP11even can propagate in the wavelength range from 500nm to 1890nm in the two-mode PCF which is nine times as wide as that in elliptical core fibers. The theory of highly birefringence two-mode PCF for constituting fiber sensor is also discussed. According to the structure proposed, we successfully fabricate the highly birefringent two-mode PCF with stack-drawing technique and gas-inert pressurization control at furnace temperature 1900°C and gas-inert pressure 900pa. They could extend significantly the application range of these two-mode devices and open up new possibilities.
