(Color online) A 1.5 mm long, 40 μm wide laser shown with an integrated DBR grating of width 50 μm and length 300 μm.
(Color online) A power vs. current curve obtained from the cleaved facet of a laser of width 40 μm and length 1.5 mm. A maximum power of 1.7 W is recorded at 3.1 A of current.
(Color online) The emission spectra obtained at various current levels is shown. The laser began to lase on a single wavelength mode at 974.8 nm. The peak wavelength began to red shift with increasing current injection.
(Color online) The linewidth of the single wavelength mode is measured at various power levels. A minimum linewidth of 220 kHz is recorded at an output power of 200 mW.
