Abstract :
A dual wavelength narrow line-width fiber grating ring-cavity laser is reported. The output power of the two ports are up to 3.65 dBm at 1560.76 nm and 2.44 dBm at 1562.08 nm. The suppressive ratios between the two wavelengths are up to 32 dB and 40 dB respectively. Their line-widths are both 0.1 nm.
