中文摘要	molecular beam epitaxy-grown self-assembled in(ga)as/gaas and inas/inalas/inp quantum dots (qds) and quantum wires (qwrs) have been studied. by adjusting growth conditions, surprising alignment. preferential elongation, and pronounced sequential coalescence of dots and wires under specific condition are realized. the lateral ordering of qds and the vertical anti-correlation of qwrs are theoretically discussed. room-temperature (rt) continuous-wave (cw) lasing at the wavelength of 960 nm with output power of 3.6 w from both uncoated facets is achieved fi-om vertical coupled inas/gaas qds ensemble. the rt threshold current density is 218 a/cm(2). a rt cw output power of 0.6 w/facet ensures at least 3570 h lasing (only drops 0.83 db).
