附注	an inas/in0.73ga0.27as/in0.53ga0.47as/in0.53al0.235ga0.235as quantum dashes-in-a-step-well (qdswell) structure grown via molecular beam epitaxy has been studied. it is observed that the photoluminescence (pl) emission wavelength of such a structure can be as long as 2.12 mu m at room temperature (rt). this is the longest emission wavelength of inas qdashes to be realized at rt. the electron and hole energy levels of the inas/in0.73ga0.27as/in0.53ga0.47as/in0.53al0.235ga0.235as qdswell structure have been calculated using effective-mass envelope-function theory. the calculated transition energy ee1-hh1 (from the first electron energy level e1 to the first heavy-hole energy level hh1) agrees with the measured pl emission peak position quite well. it is found that qdswell is an alternative structure for realizing lasers with wavelengths beyond 2 mu m at rt.
