Definitions for light source components
1. Forward Biased LED- A process when a positive voltage is applied to the p region and a negative voltage to the n region.
2. Incoherent Light- Light in which the electric and magnetic fields of photons are completely random in orientation. Typically emitted from light bulbs and LEDs.
3. Laser-(light amplification by stimulated emission of radiation) used to provide the high-powered, tightly controlled light wavelengths necessary for high-speed, long-distance optical fiber transmission.
4. Output Pattern-is the energy couples into the core of the optical fiber.
5. Output Power- allows transmission distances.
6. Modulation Speed- is something that can limit the performance of a fiber-optic communication system.
7. Core Diameter Mismatch- will cause confusion to the system that you are sending the data from because light will reflect and come back to the system that you sent it from causing that system to process that data.
8. Current- The flow of electrons in a conductor.
9. PIN Photodiode-is manufactured to offer better performance than a regular photodiode. The better performance comes in the form of improved efficiency and greater speed.
10. Avalanche Photodiode- This photodiode works just light an avalanche being that a small bundle of photons can trigger an avalanche of electrons.
11. Responsivity- describes how well the photodiode converts a wavelength or a range of wavelengths of optical energy into electrical current.
12. Optical Subassembly-guides the light energy from the optical fiber to the photodiode.
13. Dynamic Range- The difference between the max and min optical input power that an optical receiver can accept.
14. Operating Wavelength- Fiber optic receivers that are designed to operate within a range of wavelengths.
15. Fiber-Optic Coupler- Is a device that combines or splits optical signals.
16. Optomechanical Switch- Redirects an optical signal by moving fiber or bulk optic elements by means of mechanical devices.
17. Optical

    LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor., which emits light when activated. When a fitting voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semi-conductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern. Appearing as practical electronic components in 1962, [9] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.…

    Gigabit) single-mode communications links. Chromatic dispersion is the effect of having a wide spectrum of light as the single-mode light source, and as result have light rays of traveling at slightly different speeds due to differing wavelengths. The differences in light ray speeds result in the equivalent of timing jitter at the receiver. Chromatic dispersion is caused by waveguide dispersion and material dispersion.…

    Acoustic and ultrasonic microscopes, compound microscopes, and fluorescent and UV microscopes are available. Acoustic and ultrasonic microscopes use sound waves to create images of the sample. Compound microscopes use a single light path. These types of microscopes can have a single eyepiece (monocular) or a dual eyepiece (binocular). Compound microscopes have low depth perception but high resolution and magnification. Fluorescent microscopes and UV microscopes use high-energy and short-wavelength light to excite electrons, causing them to shift to higher orbits. When the electrons fall back to their original energy levels, they emit lower-energy and longer-wavelength light.…

    Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal. An optic-fibre is a small fibre no thicker than a human hair, either made of glass or plastic that is transparent and flexible. The light inside the fibre-optic cable forms an electromagnetic carrier wave that is modulated to carry information. Fibre-optic telecommunications offers the longest and highest bandwidth (data transfer) of any other form of communication. The availability of fibre-optic technology has replaced a lot of the copper wire communications in core networks in developed countries. The modern day Fibre-optic cable was first developed by Gerhard Bernsee of Schott Glass in Germany in 1973. After this in the early 90’s a development of the photonic crystal-fibre these are much better because they have much higher power than the early glass fibre and also their wavelength-dependent can be manipulated to provide better performance. These were first available in 2000 and with this technology the first Fibre-Optic Telecommunications System was developed. Fibre optic telecommunications have three main uses the internet; optic fibres allow for an extremely fast bandwidth this is normally used by big companies and the government, digital television; optic fibre allows for a perfect quality at all times that never cuts out which is crystal clear and never cuts out, and finally telephones; Once again used for perfect quality between long distances it was the original use for fibre optic telecommunication. ‘The glass in optical fibres is…
