Abstract

A low threshold current (≈30 mA) 1.3µm (InGaAsP) second order DFB laser with a ridge structure made by liquid phase epitaxy is reported. The low threshold results from : optimized heterostructure and grating profile, good tuning of the DFB wavelength with the peak gain wavelength, and the proper LPE regrowth conditions on the grating.
