Abstract

The re-growth free single mode lasers based on etched slots suitable for photonic integration are presented in this paper. The fabricated 650μm long laser exhibits a threshold current and a slope efficiency of about 32mA and 0.12mW/mA, respectively. The stable single mode operation has been observed with a side mode suppression ratio (SMSR) over 50dB at a current injection of 100mA for the fabricated laser. Such a laser integrated with electroabsorption (EA) modulator is also demonstrated. The integrated device has an extinction ratio over 10 dB at 2.2V driving voltage with the lasing wavelength of around 20nm positive detuning relative to the gain peak. The bandwidth measured is about 3GHz for the integrated device.
