Experimental Demonstration of Wavelength-tunable In-Series DFB Laser Array with 100-GHz Spacing

We have proposed and experimentally demonstrated a four-channel wavelength-tunable in-series DFB laser array with 100-GHz channel spacing. Compared to the in-parallel laser array, the optical combiner is not utilized and the extra power loss induced by the combiner is avoided. A linearly chirped Bra...
