摘要
A novel structure reducing diameter polarization maintaining optical fiber with high birefringence and strength is introduced. The fiber is fabricated through using modified chemical vapor deposition （MCVD） method, which is able to produce the optimum predicted eharacter-1 shaped fiber structure. As a result, a low-loss fiber with beat length close to 2.0 mm at 1310 nm wavelength and extinction ratio approximately -25 dB has been produced. The process is both simple and reproducible.
