An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video display.
Laser diode
A laser diode, or LD also known as injection laser diode or ILD, is an electrically pumped semiconductor laser in which the active laser medium is formed by a p-n junction of a semiconductor diode similar to that found in a light-emitting diode.
Thunderbolt (interface)
Thunderbolt is the brand name of a hardware interface developed by Intel that allows the connection of external peripherals to a computer.
Light-emitting diode
A light-emitting diode (LED) is a two-lead semiconductor light source.
Optical disc drive
In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs.
Photodiode
A photodiode is a semiconductor device that converts light into current.
Indium phosphide
Indium phosphide (InP) is a binary semiconductor composed of indium and phosphorus.
Gallium arsenide
Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic.
Opto-isolator
In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light.
Photoresistor
A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor.
Fiber laser
A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium.
LED art
In early 2007, there was a bomb scare in Boston, Massachusetts in the United States caused by a guerrilla marketing campaign.
Direct and indirect band gaps
In semiconductor physics, the band gap of a semiconductor is always one of two types, a direct band gap or an indirect band gap.
Electro-optics
Electro-optics is a branch of electrical engineering and material physics involving components, devices (e.g. Lasers, LEDs, waveguides etc.) and systems which operate by the propagation and interaction of light with various tailored materials.
