We develop a self-consistent, microscopic theory of coherent resonant secondary emission From semiconductor microcavities in the normal-mode-coupling regime.

In recent years, many techniques have been developed for the design of Finite Impulse Response (FIR) digital filters.

At any semiconductor heterojunction there is an interface dipole associated with quantum-mechanical tunneling, which depends on the band "lineup" between the two semiconductors.

The interaction of electron beams is studied and the two cases of two thin annular beams coaxially disposed in a circular waveguide, and of a waveguide filled with a mixture of two electron beams,

A theory of spontaneous emission noise is presented based on classical electromagnetic theory. Unlike conventional theories of laser noise, this presentation is valid for open resonators.

A N E W type of telephone repeater known as the El has been developed recently to meet the large demand in the exchange area for an economical means of providing transmission gains of about 10 db i

Intersubband transitions stimulated by an electromagnetic wave which has a momentum in the plane of a two-dimensional electron gas (2DEG) are accompanied by a "photon-drag" current due to the mome

We present a theory for tunneling between a real surface and a model probe tip, applicable to the recently developed "scanning tunneling microscope".
