48 channels 100-GHz tunable laser by integrating 16 DFB lasers with high wavelength-spacing uniformity
arXiv (Cornell University)(2020)
Abstract
We report a 48-channel 100-GHz tunable laser near 1550 nm by integrating 16 DFB lasers. High wavelength-spacing uniformity is guaranteed by the reconstruction-equivalent-chirp technique, which enables a temperature tuning range below 20 Celsius degree.
