Abstract
Good-quality long-distance optical transmission over fiber needs lasers which emit at a single wavelength. This is almost universally realized by putting a wavelength-dependent reflector into the laser cavity, in a distributed feedback laser. In this chapter, the physics, properties, fabrication, and yields of distributed feedback lasers are described.
…and there, ahead, all he could see, as wide as all the world, great, high, and unbelievably white in the sun, was the square top of Kilimanjaro.

In the first edition of the book, the discussion continued, ‘this technique is not used typically for commercial lasers.’ and went on to explain that it required e-beam grating fabrication, which was not commercially feasible. It now is commercially feasible, and many companies use it. Proficiscitur in tempore!
