The feasibility of a group‐velocity matched‐fiber Raman wavelength converter using extended birefringent fiber has been demonstrated, in which high‐power pumping laser diodes are used to achieve sufficient four‐wave mixing (FWM) Raman conversion. Based on our proposed novel model, the power intensity and temporal properties of the converted wave (10 Gb/s and 20 Gb/s, from C ‐band to L ‐band) have been demonstrated. The ultra‐wide Raman gain spectrum and the tunability of the fiber birefringence make our model extremely suitable for broadband wavelength‐convertible lightwave communication. © 2003 Wiley Periodicals, Inc.
