Since its invention in 1962, the semiconductor laser has come a
long way. Advances in material purity and epitaxial growth
techniques have led to a variety of semiconductor lasers covering a
wide wavelength range of 0. 3- 100 ILm. The development during the
1970s of GaAs semiconductor lasers, emitting in the near-infrared
region of 0. 8--0. 9 ILm, resulted in their use for the first
generation of optical fiber communication systems. However, to take
advantage of low losses in silica fibers occurring around 1. 3 and
1. 55 ILm, the emphasis soon shifted toward long-wavelength
semiconductor lasers. The material system of choice in this
wavelength range has been the quaternary alloy InGaAsP. During the
last five years or so, the intense development effort devoted to
InGaAsP lasers has resulted in a technology mature enough that
lightwave transmission systems using InGaAsP lasers are currently
being deployed throughout the world. This book is intended to
provide a comprehensive account of long-wave length semiconductor
lasers. Particular attention is paid to InGaAsP lasers, although we
also consider semiconductor lasers operating at longer wave
lengths. The objective is to provide an up-to-date understanding of
semicon ductor lasers while incorporating recent research results
that are not yet available in the book form. Although InGaAsP
lasers are often used as an example, the basic concepts discussed
in this text apply to all semiconductor lasers, irrespective of
their wavelengths.
