Abstract
The potential advantages of GaInAs/InP multiquantum well (MQW) structures over bulk material for improving the static properties of buried heterostructure (BH) lasers are demonstrated. Using a highly uniform metalorganic vapor phase epitaxy (MOVPE) growth, an optimized simple separate confinement heterostructure (SCH) MQW layer stack, and the buried ridge stripe (BRS) structure, improved static performances over any bulk or unstrained MQW long wavelength laser were obtained. An extremely low threshold below 2 mA was obtained in short cavity lasers, the threshold current was only 10.6 mA and 110 mW continuous-wave (CW) maximum optical power was observed using 90%/10% reflectivity coatings.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
