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 100Ã…, 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 lengt ....etc

INTRODUCTION
When we talk about optical communication, most people think about optical-fiber. But optical communication is also possible without optical-fiber. We know that light travels through air for a lot less money. This makes possible the optical communication without optical-fiber. Optical communication without fiber is known as Free Space Optics. It is used due to economic advantages. Since the introduction of internet the backbone traffic is increasing at the rate greater than 100%, hence the owner of the backbone ....etc

INTRODUCTION
With the growth of computing technology the need of high performance computers (HPC) has significantly increased. Optics has been used in computing for a number of years but the main emphasis has been and continues to be to page link portions of computers, for communications, or more intrinsically in devices that have some optical application or component (optical pattern recognition etc.)Optical computing was a hot research area in 1980’s.But the work tapered off due to materials limitations tha ....etc

ABSTRACT
Optical computing means performing computations, operations, storage and transmission of data using light. Instead of silicon chips optical computer uses organic polymers like phthalocyanine and polydiacetylene.Optical technology promises massive upgrades in the efficiency and speed of computers, as well as significant shrinkage in their size and cost. An optical desktop computer is capable of processing data up to 1,00,000 times faster than current models.

ABSTRACT
Free space optics ( FSO ) is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice, and video communications through the air , allowing optical connectivity without deploying fiber optic cables or securing spectrum licenses. FSO system can carry full duplex data at giga bits per second rates over Metropolitan distances of a few city blocks of few kms. FSO, also known as optical wireless, overcomes this last-mile access bottleneck by sending high “b ....etc

Vertical Cavity surface Emission Lasers (VCSEL) are lasers that emit light from their surface in contrast with regular ???edge emittersâ„¢. 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 circul ....etc

In an information society, where the primary preoccupation in life is the generation, dissemination and management of information, there is an ever-increasing appetite for computing power and interconnection bandwidth. In the coming era of teraflop computing and multi terabyte storage, multiple processors and large data stores will be interconnected with up to terabit per second aggregate bandwidth over distance extending from just centimeters to hundreds of meters. VCSEL based optical interconnections can meet the speed, distance and density d ....etc

ABSTRACT
Smart pixels, the integration of photodetector arrays and processing electronics on a single semiconductor chip, have been driven by its capability to perform parallel processing of large pixelated images and in real-time reduce a complex image into a manageable stream of signals that can be brought off-chip. In recent years, optical modulators and emitters have been integrated with photodetectors and on-chip electronics. The potential uses for smart pixels are almost as varied as are the designs. They can be used ....etc
