摘要：

We report a tunable dual-wavelengths-switching fiber grating laser by exploiting the large homogeneous gain broadening in erbium (Er)-doped fiber to suppress simultaneous lasing, Wavelength switching was accomplished through a novel design which has two overlapping cavities sharing a single-gain medium, The loss corresponding to one of the lasing wavelengths can be modulated via an optical chopper, Output power of about 6 mW and extinction ratio up to 50 dB were observed, The lasing wavelengths were tunable and switching was demonstrated for wavelength separations ranging from 0.35 to 23.5 nm.
