Fig. 1. Experimental setup.
Fig. 2. Observed output spectrum of the three-channel dual-wavelength signals at the same time. Corresponding wavelength interval for Channels 1–3 are 4 pixels (0.21 nm), 12 pixels (0.65 nm), and 18 pixels (0.98 nm), respectively.
Fig. 3. Observed output spectrum of the three-channel dual-wavelength signals at different times. Three channels can independently and simultaneously realized dual-wavelength lasing.
Fig. 4. Measured fluctuation of laser output power. Channel 1, wavelength interval 4 pixels (0.21 nm); Channel 2, wavelength interval 12 pixels (0.65 nm); Channel 3, wavelength interval 18 pixels (0.98 nm).
Fig. 5. Measured output spectrum at fixed wavelength spacing of 4 pixels for Channel 1 and at 10 ×
