As early as 1963, it was proposed that heterojunctions could be used to produce a waveguiding structure with the desired property of optical confinement [12.1, 2]. At about the same time, others proposed using

Distributed Feedback Lasers,n optical integrated circuit, in which the laser diodes are monolithically integrated within the semiconductor wafer, it is usually very difficult to form such reflecting surfaces. They can be formed by etching or cleaving, as described in Chap. 12. However, the planar surface of the wafer is then d
