.Design of a new type high birefringence photonic crystal fiber[J].Optoelectronics Letters,2008,4(1):19-22 Design of a new type high birefringence photonic crystal fiber CHEN Ming YANG Si-gang YIN Fei-fe CHEN Hong-wei XIE Shi-zhong Department of Electronic Engineering of Tsinghua University, Beijing 100084, China Abstract:       A High birefringence microstructure fiber with four big elliptical air holes is investigated by using the finite-difference frequency-domain (FDFD) method. Based on the numerical simulations, the influence of the air-hole size and pitch upon the mode birefringence is analyzed. The work may be helpful for the design and fabrication of high birefringence PCFs. Hits: 3614 Download times: 202 View Full Text    Download reader
