英文摘要	A novel integration technique has been developed using band-gap energy control of ingaasp/ingaasp multi-quantum-well (mqw) structures during simultaneous ultra-low-pressure (22 mbar) selective-area-growth (sag) process in metal-organic chemical vapour deposition. a fundamental study of the controllability of band gap energy by the sag method is performed. a large band-gap photoluminescence wavelength shift of 83nm is obtained with a small mask width variation (0-30 mu m). the method is then applied to fabricate an mqw distributed-feedback laser monolithically integrated with an electroabsorption modulator. the experimental results exhibit superior device characteristics with low threshold of 19 ma, over 24 db extinction ratio when coupled into a single mode fibre. more than 10ghz modulation bandwidth is also achieved, which demonstrates that the ultra-low-pressure sag technique is a promising approach for high-speed transmission photonic integrated circuits.
