Abstract :
Integration of semiconductor nano-structures (NS) with conventional optoelectronic devices is important to draw technical breakthrough in their performance. One of the interesting examples in semiconductor lasers is realizing a gain-coupled distributed-feedback (GC-DFB) laser using V-groove quantum-wire (QWR) arrays. In this paper we have tried to get GC-DFB lasers to operate at room temperature (RT) by (1) eliminating the process for grating overgrowth and (2) modulating the QWR active grating profiles.
