Abstract :
Summary form only given. The maximum CW powers for single-mode diode lasers are limited by tolerable current and photon densities in their active regions. The maximum width of a single-mode laser active region is inversely proportional to /spl radic//spl Delta/n/sub B/, where /spl Delta/n/sub B/ is the built-in refractive index step at the active region boundary. In this paper, /spl lambda/=1.5 /spl mu/m InGaAsP/InP SCH 3QW broad-waveguide (600 nm) ridge waveguide lasers with low values of /spl Delta/n/sub B/ (5 - 7/spl times/10/sup -3/) have been investigated.
