Abstract
Data are presented on InGaAsP/InP planar buried heterostructure (PBH) distributed feedback (DFB) lasers operating at 1.3 μm. A four-step MOVPE process and holographic lithography are employed to fabricate these lasers. The CW laser threshold and the slope efficiency from these lasers are 9 mA and 0.23 mW mA-1 per facet at room temperature. Single-longitudinal-mode operation with side-mode suppression of more than 35 dB is obtained at 5 mW.
