摘要: This paper proposes a switchable wavelength fiber laser (SWFL) based on an arrayed waveguide grating (AWG) and gain-saturated reflective semiconductor optical amplifier (RSOA). The SWFL was experimentally implemented in the C- L-bands. In order to achieve narrow-linewidth oscillation, driven by bidirectional injection-locked RSOAs. RSOA operated region, using gain compression properties obtain uniform power over wide bandwidth. Based this configuration, we obtained 40 C-band international telecommunication unit (ITU) wavelengths with 100-GHz channel spacing. displayed narrow 3-dB bandwidth ( 0.22 dB, ΔPmax 66 ΔSMSR < 1 dB). peak-power stabilities were ±0.24 dB ±0.01 nm, respectively, at room temperature h period.
