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

Researchers at the University of California, Berkley, have developed a way to grow nanolasers on a piece of silicon which is believes to pave the way for new generation of laser processors.

In fact the silicon is bad at generating light. Scientists had previously tried to develop chips made of silicon and so-called II-V (three-five) semiconductor materials, but this approach has problems of its own.

Lead researcher and UC Berkeley grad student Roger Chen said in a press release: Growing II-V semiconductor films on silicon is like for ....etc

Alternative fuels, known as non-conventional or advanced fuels, are any materials or substances that can be used as fuels, other than conventional fuels like; fossil fuels (petroleum (oil), coal, and natural gas), as well as nuclear materials such as uranium and thorium, as well as artificial radioisotope fuels that are made in nuclear reactors.

Some well-known alternative fuels include biodiesel, bioalcohol (methanol, ethanol, butanol), chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natura ....etc

Seminar Topic on Fuels


Types of fuels

Presently crude oil is most sought after for marine use.
Broadly classified into three types:
a) Paraffin base: residue > 5% paraffin wax.
b) Asphalt base: contains <2% paraffin wax and mainly composed of asphalt. (Naptha)
c) Mixed base: paraffin wax >2% <5% mixed intimately with asphalt.
The type obtained depends on the source and also determines the type of refining necessary and nature of end products produced.
Paraffin and gas oil are known as distillat ....etc

nuclear fuels using lasers ppt

Laser enrichment processes have been the focus of interest for some time. They are a possible third-generation technology promising lower energy inputs, lower capital costs and lower tails assays, hence significant economic advantages. One of these processes is almost ready for commercial use. Laser processes are in two categories: atomic and molecular.

Development of the Atomic Vapour Laser Isotope Separation (AVLIS, and the French SILVA) began in the 1970s. In 1985 the US Government backed it as the new techno ....etc

Vertical Cavity surface Emission Lasers (VCSEL) are lasers that emit light from their surface in contrast with regular ???edge emitters . Also they have got a vertical cavity , as the name suggests, which enables surface emission.???Vixels??? , as they are commonly called ,have several superior characteristics compared to their edge emitting counter parts.

VCSEL Semiconductor micro laser diodes which emit light perpendicular to their PN junction in a cylindrical beam vertically from the surface of a fabricated wafer and feature circular lo ....etc

Tunable lasers


Tunable lasers as the name suggests are lasers whose wavelengths can be tuned or varied. They play an important part in optical communication networks. Recent improvements in tunable laser technologies are enabling highly flexible and effective utilization of the massive increases in optical network capacity brought by large-scale application of dense wavelength division multiplexing. Several tunable laser technologies have emerged, each with its own set of tradeoffs with respect to the needs of particu ....etc
