We present buried heterostructure QC lasers with optimized design, an improved waveguiding scheme and better heat dissipation for high temperature CW operation. The laser's lower waveguide cladding and waveguide core consisted of ternary InAlAs and InGaAs layers grown lattice matched to an n-doped InP substrate by molecular beam epitaxy (MBE). The active region is a repetition of 35 stages, each stage comprising a four quantum well active zone designed for emission at 9.1 /spl mu/m.
