Abstract

We report the results of laser arrays with 32 wavelengths in 0.8 or 0.4-nm wavelength spacing. For the 0.8-nm spaced arrays, we demonstrate that a much larger range of reflection peak spacing can be realized in sampled grating DBR (SGDBR) mirrors, in comparison with previous designs. For the 0.4-nm spaced arrays, we show to our knowledge the best as-fabricated wavelength control for MWLAs that are feasible for DWDM applications
