semiconductor optical amplifiers
SPIE Newsroom, 1990Semiconductor laser amplifiers have now proved their ability to improve the performance of single-mode fiber communication systems, at least in the laboratory stage. After a brief background review of optical amplification in communication systems, the principle of operation and main device characteristics of semiconductor optical amplifiers are ...

Metal–Semiconductor Junctions and Semiconductor Heterostructures
2001In comparison to the solid-vacuum interface, i.e. the clean, well-defined surface of a solid, other solid interfaces are of much more practical importance. The solid-liquid interface, for example, plays a major role in electrochemistry and biophysics. Studies of that particular interface have a long tradition in physical chemistry. A detailed treatment

Semiconductor technologies and semiconductor memories
SIMULATION, 1976In this article, we discuss the semiconductor techno logies from which microprocessors are constructed and the semiconductor memories with which microprocessors are commonly used. We will discuss the characteristics of the technologies and memories from the user's point of view and will not discuss either the inner workings or the manufacturing ...

The European Physical Journal B, 2007
We theoretically calculate the Josephson current for two superconductor/ferromagnetic semiconductor (SC/FS) bilayers separated by a semiconductor (SM) layer. It is found that the critical Josephson current IC in the junction is strongly determined by not only the relative orientations of the effective exchange field \({\bf h}\) of the two bilayers and ...
