Abstract :
Summary form only given. Recently, a room temperature buried heterostructure DFB laser with an emission wavelength of 2.03 μm was demonstrated. The laser structure was grown with InGaAsP (λ 1.5 μm) barriers which lead to a gain peak at 1.995 μm In this work, we demonstrate that by using InGaAs (λ 1.67 μm) barriers the gain peak of the lasers was extended to 2.03 μm, and by detuning the grating of the DFB, a room temperature CW emission of almost 2.06 μm was achieved
