In Chapter 4 we have presented a survey of fiber technology and of the technology needed to fabricate optical filter and wavelength multiplexer and demultiplexers for telecommunications.
In this chapter we will present a survey of the so-called integrated technology that is the technology leveraging planar processes to manufacture electronics and optical components.
The first part of the chapter is devoted to optical planar components built on the III–V platform.
The most important of those components is the semiconductor laser, both for the huge number of telecom and non-telecom applications and for the key role it plays in telecom equipments.
We will ...
