Abstract :
Summary form only given. The advantages of using the complex coupled distributed feedback (DFB) laser structure are mainly its high single-mode yield and good selectivity, among others. The lasers described here were grown by MOCVD with a multiple quantum well (MQW) active region consisting of six compressively strained InGaAsP quantum wells. After MOCVD regrowth, both 2 /spl mu/m-wide self-aligned ridge waveguide (RWG) and 1.3-/spl mu/m-wide buried ridge structures (BRS) lasers were fabricated.
