power with respect to the backward power measured from the photodiode

attached with the laser diode. The normalized power changes 0.5 dB when the

temperature change spans 46 to 62 8C due to the small change on the reflection

when operating below threshold. With the proper choice of adhesives, the

lifetime of the laser does not degrade as tested over several years.

16.5.5 Coupling to Integrated Optics

Fiber-to-waveguide connection is one of the key technologies in the realiza-

tion of guided-wave optical devices. Optical telecommunication systems are the

leading force for these technologies. Most of the applications in optical telecom-

munication are based on the use of random polarized light, because the available

PM fibers are impractical and expensive ...
