Abstract

A simple architecture to achieve a stable dual-wavelength fibre laser that can lase at room temperature with a narrow linewidth is demonstrated using stimulated Brillouin scattering in conjunction with a dual-pass amplification configuration. The dual-wavelength Brillouin laser used a 100 m long photonic crystal fibre (PCF) as a gain medium and a broadband fibre Bragg grating (FBG) operating in the C-band region to allow dual-pass operation. A stable room temperature dual-wavelength fibre laser with a power of nearly 10 mW and a signal-to-noise ratio (SNR) of more than 21 dB was obtained. The stable dual-wavelength lasing oscillation had a wavelength spacing of 0.08 nm and could be tuned within a range of approximately 35 nm, from 1530 to 1565 nm. The proposed laser can operate at any wavelength depending on the Brillouin pump (BP) wavelength and the FBG reflection region used.
