From: High channel count and high precision channel spacing multi-wavelength laser array for future PICs
(a) The measured lasing spectra of one 60-wavelength array which is corresponding to Array No.5 in Fig. 3. One laser is dual mode. (b) The lasing wavelengths and the linear fitting curve with the slope of 0.7887 nm/channel (the deigned value is 0.80 nm/channel). (c) The wavelength residuals after linear fitting which is also plotted in Fig. 3 Array No.5 for detailed statistical data.
