Basic Principles of Light Emission in Semiconductors,their convenience, gas lasers are frequently used in the laboratory to evaluate waveguides or other integrated-optic devices; however, semiconductor lasers and light-emitting diodes are the only practical light sources for use in optical integrated circuits, due to their small size and compatibility

Semiconductor Lasers,emission is that it is possible to design a light source in such a way that stimulated emission of photons will predominate over both spontaneous emission and absorption. If a resonant reflecting structure such as a pair of plane, parallel end faces is provided, a lasing mode can be established and

Heterostructure, Confined-Field Lasers,tantial reduction of threshold current density and a corresponding increase in efficiency. As early as 1963, it was proposed that heterojunctions could be used to produce a waveguiding structure with the desired property of optical confinement , 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

Quantum-Well Devices,ice. When the dimensions of the structure are reduced to the point at which they are approaching the same order of magnitude as the electron wavelength some unique properties are observed. This is the case with a class of devices that have come to be known as “quantum well” devices, which feature ve
