The re-growth free single mode lasers based on etched slots suitable for photonic integration are presented in this paper. The fabricated 650 μm long laser exhibits a threshold current and a slope efficiency of about 32 mA and 0.12 mW/mA, respectively. The stable single mode operation has been observed with a side mode suppression ratio (SMSR) over 50 dB at a current injection of 100 mA 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 20 nm positive detuning relative to the gain peak. The bandwidth measured is about 3 GHz for the integrated device.
本文介绍了基于适用于光子集成的蚀刻槽的无再生长单模激光器。制造的650μm长激光器的阈值电流和斜率效率分别约为32 mA和0.12 mW/mA。对于制造的激光器，在100 mA的电流注入下观察到稳定的单模运行，边模抑制比（SMSR）超过50 dB。还展示了这种与电吸收（EA）调制器集成的激光器。该集成器件在2.2V驱动电压下的消光比超过10 dB，激射波长相对于增益峰值有大约20 nm的正失谐。测量的集成器件带宽约为3 GHz。
