4. Conclusion

After a brief review of semiconductor transmitters and their structures, we set out the principles for measuring their specific parameters. There wasn't enough room here for an exhaustive review of all possible measurements. Readers will find a fact sheet [Doc. R 1 178v2] at the end of this article.

Optical telecommunications applications and, in particular, the development of very high-speed systems linked to the explosion of the Internet and the growing demand for bandwidth, have generated most of the research activity on semiconductor light emitters and, in particular, lasers. The latter are being asked for more extensive functionalities, as well as higher performance in terms of emitted power and bandwidth. Last but not least, tunable lasers are becoming...
