Fig. 1. Schematic diagram of the MWFL setup based on the bidirectional Lyot filter.
Fig. 2. (a) Evolution of multiwavelength deterioration due to HWP rotation. (b) Measured bandwidth and OSNR of the multiwavelength spectrum from 0° to 90° with a 15° interval of HWP rotation.
Fig. 3. Degraded lasing lines and flatness due to lower SOA currents of 475, 375, 275, and 175 mA.
Fig. 4. (a) Best multiwavelength spectrum at 575 mA of SOA current. The wavelength separation of 0.1 nm is clearly shown in the inset figure. (b) Narrower wavelength region and lower OSNR without PC3 in the setup.
Fig. 5. Measurement of power stability within 200 min in different wavelength ranges of (a) 1562.5–1563.5 nm, (b) 1563.5–1564.5 nm, and (c) 1564.5–1565.5 nm.
Fig. 6. (a) Peak power against time for the largest deviation within the three wavelength ranges. (b) Wavelength drift observation within 200 min.
