M. Dion et al., A STUDY OF THE TEMPERATURE SENSITIVITY OF GAAS-(AL,GA)AS MULTIPLE-QUANTUM-WELL GRINSCH LASERS, IEEE journal of selected topics in quantum electronics, 1(2), 1995, pp. 230-233
We have measured the temperature sensitivity, T-0, of GaAs-(Al,Ga)As,
GRINSCH, multiple quantum-well (MQW) lasers with different numbers of
quantum wells ranging from one to ten. Our data suggests that there is
an optimum number of wells, namely five, where T-0 is highest, Using
a temperature-dependent model based on drift-diffusion equations, we h
ave systematically analyzed the temperature sensitivity of a MQW GaAs-
(Al,Ga)As laser, The T-0 versus well-number behavior observed experime
ntally is verified, and the important temperature-dependent factors ar
e identified.
