A Wavelength Tunable DBR Laser Integrated with an Electro-Absorption Modulator by a Combined Method of SAG and QWI

Abstract
We report a wavelength tunable electro-absorption modulated DBR laser based on a combined method of SAG and QWI.The threshold current is 37mA and the output power at 100mA gain current is 3.5mW.When coupled to a single-mode fiber with a coupling efficiency of 15%,more than a 20dB extinction ratio is observed over the change of EAM bias from 0 to -2V.The 4.4nm continuous wavelength tuning range covers 6 channels on a 100GHz grid for WDM telecommunications. -
