According to science fiction, in the future, our technology tools would run “at the speed of light”, but, is it possible?
But first what is the electronics?
Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components (such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors), associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.
The science of electronics is considered to be a branch of physics and electrical engineering.
The nonlinear behavior of active components and their ability to control electron flows makes the amplification of weak signals possible. Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.
Then, the electronics make use of the electron to send and receive information along an electric circuit.
Nice… But what is the photonic?
This is the dream of all people who know electronics, it’s a basic idea, it’s about using photons (light) instead of electrons
It seems a simple idea at first glance, no? But the fact is that it is a revolutionary idea, which marks a now and a later in the informatics. The photon can send, receive, save, load, drop and transport information most most fast and better than the electrons( At the speed of light!!!), this makes our computers, laptops, smartphones, tablets, game consoles, televisions, and all electronic devices work at a speed that we can not imagine, very very very fast, so much so, that currently there are no processors that can process the information at such speed. This represents a revolution, the technology revolution, this can change our lives at all levels.
For example, photonic networks have three very important threads – capacity, speed, and range. Firstly, they can move a larger amount of data at longer distances. Secondly, latency between two endpoints on the network is reduced if we use a photonic network instead of the regular, electric one. When we use electric current, data travel at the speed which is at around 10% speed of light. This means that data travels around 30.000 km per second. Contrarily, photonic signals travel at least ten times faster.
Last but not least, it is known that light beams do not interfere or mix. In this case, it is proven that each light beam has its content and they carry that content through signals on wavelengths which are simultaneous and multiple. These wavelengths are also known as WDM or wavelength division multiplexing.
