The vertical cavity surface emitting laser (VCSEL) is a relatively new se- conductor laser device, especially applicable to ?ber-optic networks in the 21st century. About 25 years have passed since its invention, and devices for Gigabit Ethernet are now being mass-produced. It is expected that VCSELs will open up a new era of very-high-speed ?ber-optic networks and a wide range of application areas. VCSEL have many advantages, such as: (i) monolithic and high-yield f- rication;(ii)extremelylowthresholdandsmallpowerconsumption;(iii)hi-...

Semiconductor Quantum Well Intermixing is an international collection of research results dealing with several aspects of the diffused quantum well (DFQW), ranging from Physics to materials and device applications. The material covered is the basic interdiffusion mechanisms of both cation and anion groups as well as the properties of band structure modifiations. Its comprehensive coverage of growth and pos-growth processing technologies along with its presentation of the various interesting and advanced features of the DFQW materials make this book an essential reference to the study of QW...
