Small-signal modelling of the transistor laser including the quantum capture
and escape lifetimes



The transistor laser was rst introduced in , and it was
predicted that this device could have a high-speed modula-
tion bandwidth of up to 100 GHz . In the transistor laser
(TL), a quantum well (QW) is embedded in the base of the
bipolar junction transistor (BJT) and acts as an optical col-
lector. The stimulated recombination causes compression in
the I-V characteristics of t ....etc

Quantum Wells, Quantum Wire, and Quantum Dots

I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.

ABSTRACT
Quantum Dots(QDs) are small conductive regions in a semiconductor, containing a number of charge carriers(from one to thousand) that occupy well defined discrete quantum states. They have typical dimensions between nanometers to a few microns .When the space at any side, around a material shrinks to 100 , quantisation of the energy levels at the reduced side will occur. In quantum dots electrons are confined in all directions to a volume in space with dimensions on the order of their de Broglie wave length, ie, the ....etc

Applications of Majority Gates with Quantum-Dot Cellular Automata(QCA)

ABSTRACT
Majority gate-based logic is not normally explored with standard CMOS technologies,primarily because of the hardware inefficiencies in creating majority gates.As a result,not much effort has been made towards the optimization of circuits based on majority gates.We are exploring one particular emerging technology,quantum-dot cellular automata(QCA),in which the majority gate is the fundamental logic primitive.One of its main application is a simple and in ....etc

Definition

Quantum Dot Lasers can be considered as a quantum leap in the development of lasers. Quantum Dots improve basically the laser emissions. This property of Quantum Dots is well utilized for fiber optic communication, which is now the leading subject under research and development. Quantum Dots are thus very well used in applications fiber optic communication. The remaining major division of the field of quantum electronics deals with the interactions of coherent light with matter and again leads to a wide range of all-optical and op ....etc
