Our approach involves a "technology transfer" in the sense that, in order to tackle the problem belonging to quantum optics, we make use of results obtained recently in the study of the so-called nondiffracting localized solutions to the classical wave equation....
Another way to make photons, known as chemiluminescence, involves chemical reactions. When these reactions occur in living organisms such as bacteria, fireflies, squid and deep-sea fishes, the process is known as bioluminescence. At least two chemicals are required to make light. Chemists use the...
If many atoms are cooled to a very low temperature confined in a small volume, they can become indistinguishable and behave like a single “super particle.” Physicists also call this a Bose-Einstein condensate or quantum gas. Photons condense based on a similar principle and can be cooled usi...
It allows you to focus a copy of the image in a specific place. Although you can't really focus the image on a photocopier to make the final product more or less blurry, you can change the distance between the lens and the original or between the lens and drum to either reduce or ...
A digital computer adds and compares numbers based on a hardware element that mainly consists of transistors and capacitors. It relies on currents and electrical charges to make computations. A photonic computer, as its name suggests, uses photons instead. ...
Photons are particles that make up all types of electromagnetic radiation, including visible light and radio waves, as seen inFigure 1. One of the most important part of this spectrum for imaging isvisible light, which ranges from380-750 nanometers, as seen in the insert ofFigure 1. ...
Camera viewfinders are essential for composing and focusing photographs accurately. They allow photographers to control the composition, adjust focus, and make decisions about 10. LCD Screen A cameraLCD (Liquid Crystal Display)screen is a built-in display that serves multiple functions, includingreviewi...
A photonic integrated circuit is a chip that could contain hundreds of photonic components, components that works with light (photons).
Smart people discovered how to make those photons transmit information in the form of sequences of 1s and 0s, and we even have a language for processing those 1s and 0s: Binary code. NFC Standards We’ve set standards to define which sequences represent which ASCII characters—so devices,...
However, any savings you make on price will likely be outweighed over the long term by inferior performance. Polycrystalline silicon PV cells are less expensive and time-consuming to produce. Instead of using wafers cut from an ingot grown from a single silicon cell, polycrystalline PV cells are...
