Constant output power and low linewidth in a simple wide tuning DFB laser with multiwavelength grating

Wide tuning DFB-type oscillation from a DFB-DBR InGaAsP strained QW laser is reported. DFB modes defined by a multiwavelength grating (MWG) in the active section are selected by tuning the passive section current. Upon tuning, output power remains constant and linewidth remains lower than 5 MHz.
