The vertical-cavity surface-emitting laser (VCSEL) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.There are several advantages to producing VCSELs when compared with the production process of edge-emitting lasers. Edge-emitters cannot be tested until the end of the production process. If the edge-emitter does not work, whether due to ....etc

1. INTRODUCTION
Imagine having a high-definition TV that is 80 inches wide and less than a quarter-inch thick, consumes less power than most TVs on the market today and can be rolled up when you're not using it. What if you could have a heads up display in your car? How about a display monitor built into your clothing? These devices may be possible in the near future with the help of a technology called organic light-emitting diodes (OLEDs). OLED is a flat display technology, made by placing a series of organic t ....etc

Flexible Organic LED s


Presented By: Ryan Evans



What the Flexible Organic Light Emitting Diode Consist of :

The Top Layer is the Cathode layer made of tungsten releases electrons when current is run through it.

Emissive Layer removes electrons from the cathode layer to make light.

Conductive layer is made from a type of organic plastic that removes the electron wholes

Then the Anode Layer that consist of removing and adding electron holes while the current is running through it and i ....etc

Surface plasmon resonance
ABSTRACT

Surface plasmon resonance (SPR) is a phenomenon occurring at metal surfaces(typically gold and silver) when an incident light beam strikes the surface at a particular angle.Depending on the thickness of a molecular layer at the metal surface,the SPR phenomenon results in a graded reduction in intensity of the reflected light.Biomedical applications take advantage of the exquisite sensitivity of SPR ....etc

POLYMER LIGHT EMITTING DIODES (PLEDs)

Polymer LED (light-emitting diode) - sometimes called light-emitting polymer or polyLED - is a technology based on the use of polymer as the semiconductor material in LEDs.

Polymers are chemical substances that consist of large molecules that are themselves, made from many smaller and simpler molecules.

Polymers are largely identified with insulation.

Research institutes have come up with ideas to integrate polymers into main stream electronics as it has been established that certain poly ....etc
