…left and right).
Figure 3 shows a single line (50MHz linewidth) at each Free Spectral range (FSR) of the FabryPerot analyzer. The Fabry-Perot scanned through four FSR in the graphs. Figure 3 left and
right are indifferentiable whereas the OSA measurement in figure 1 shows a mode structure…

…the micromirror array.
The laser oscillated with a stable, single mode for each of the 4 wavelengths. The
linewidth was measured with a scanning Fabry-Perot etalon (Thorlabs SA-200-6A). The
linewidth measurement was limited by the resolution of the instrument to 7.5 MHz.
