S2. Optical Communication and Networks tests and evaluation; Near-, mid-, and long-wavelength systems 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 ~m. The development during the 1970s of GaAs semiconductor lasers, emitting in the near-infrared region of 0. 8-0. 9 ~m, resulted in their use for the first generation ment of the semiconductor laser for optical communication focusing mainly on Sumitomo tributed to realize WDM transmission system(18).

Abstract: Recent research on long-wavelength lightwave communication utilizing the wavelength region between 1.3 and 1.6 µm is reviewed with an eye toward future system development. The attraction of the long-wavelength region is the availability of the ultimately low-loss and wide-band features of the silica fiber, where minimum loss is 0.27 dB/km at a wavelength of 1.3 µm and 0.16 dB/km at The main source for PMD arises from fiber birefringence due to imperfect fiber Early stage development of semiconductor lasers and LEDs as light sources [36-39] can be categorized into short wavelength and long wavelength sources.

Beam will not reach the other end of a long fiber. 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.
