This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantum well semiconductor laser has been shown to be the semiconductor laser of choice for efficiency and thereby high power applications. The key advantage of nonlinear devices fabricated in quantum well waveguides is that they can be easily integrated with quantum well lasers. Nonlinear optical effects in GaAs/AlGaAs quantum wells have been of considerable interest for sometime. In guided-wave formats some nonlinear devices have been demonstrated; a nonlinear directional coupler has been fabricated and characterised, and a saturable absorber for a mode-locking semiconductor laser has also been demonstrated.
