Temperature dependence of gain characteristics in 1.3-/spl mu/m AlGaInAs/InP compressively strained multiple quantum well semiconductor lasers

Abstract
Summary form only given. So far 1.3 /spl mu/m AlGaInAs-InP strained MQW lasers have achieved high characteristic temperature T/sub 0/ of 120 K and high operating temperature of 185 C. In this paper, we evaluated temperature dependence of the gain characteristics in AlGaInAs-InP lasers, and found that the high T/sub 0/ was caused by the smaller temperature dependence of the spontaneous emission efficiency than that of GaInAsP-InP lasers.
