A recap of high performance AlGaInAs/InP laser development history

Abstract

We review 1.3 $\mu \mathrm{m}$ AlGaInAs/InP laser development in the early 1990s for uncooled subscriber loop operations. A similar active design has been used to make 1.3- and $1.55-\mu \mathrm{m}$ VCSELs and $1.3-\mu \mathrm{m}$ directly modulated MQW DFB lasers for 100G Ethernet application in 2000s.
