It is demonstrated a stable dual-wavelength fiber ring laser using an SOA in conjunction with an array waveguide grating (AWG). The experimental results show stable dual lasing lines with an adjustable wavelength separation and a SNR of over 30 dB under room temperature. The first channel operates a...
