| 中文摘要 | a novel butt-joint coupling scheme is proposed to improve the coupling efficiency for the integration of a galnasp mqw distributed feedback (dfb) laser with an mqw electro-absorption modulator (eam). the proposed method gives more than 90% coupling efficiency, being much higher than the 26% coupling efficiency of the common mqw-mqw coupling technique. the differential quantum efficiency of the mqw-bulk-mqw coupled device is also much higher than that of the mqw-mqw device, 0.106 mw/ma versus 0.02 mw/ma. the eam-dfb devices fabricated by the proposed method exhibit a very high modulation efficiency (12 db/v) from 0 to i v. by adopting a high-mesa ridge waveguide and buried polyimide, the capacitance of the modulator is reduced to about 0.28 pf. the experimental results demonstrate that the method can replace the conventional mqw-mqw coupling technique to fabricate high-quality integrated photonic devices.
