2^nd International Conference on Optics & Photonics June 29-30, 2022 Madrid, Spain

Photonics is the physical science of light waves. It discusses the science behind the generation, detection and manipulation of light. Photonic devices are components for creating, manipulating, or sensing light. This can include laser diodes, light emitting diodes, solar and photovoltaic cells, displays and optical amplifiers.

Photonics consists of advanced uses of lasers, optics, fiber optics and electro-optical devices in frequent and varied fields of technology - alternative energy, manufacturing, healthcare, telecommunications, environmental monitoring, homeland security, aerospace, solid state lighting and many more. Rapid advances in the number and complexity of photonic and photonic technologies have caused technicians to overload the supply. The number of engineering college degrees is declining, resulting in fierce competition for the relatively small pool of qualified optical technicians and engineers.

The word photonics developed as an outgrowth of the first practical solid-state light emitters invented in the early 1960s and fiber optics developed in the 1970s. It also relates to the emerging science of quantum information. Photonic science includes the emission, generation, modulation, transmission signal processing, amplification, switching, and detection of light. However, covering all technical applications of light across the spectrum, most photonics applications are in the near-infrared and visible light range.

Optical physics is a study of the atom and molecules. It is the study of electromagnetic radiation, the interaction and properties of this radiation with matter, in particular its manipulation and control. It differs from general optics and optical engineering, but among optical physics, applied optics and optical engineering, applications of applied optics and optical engineering devices are necessary for basic research in optical physics, and this research leads to the development of new devices and applications.

Photonics plays an important role in driving innovation in a growing number of fields. Photonics is basically the science that involves the generation of a photon (light), its detection, as well as its manipulation through transmission, emission, signal processing, modulation, switching, amplification and detection. . The application of photonics spans multiple industries, from optical data communications to imaging, lighting and displays, manufacturing, life sciences, healthcare, security and to safety.

Optical communications networks play a vital role, as there is a high demand for capacity links. DWDM, which stands for Dense Wavelength Division Multiplexing, is widely deployed on core networks to provide high-capacity transport systems. Optical components such as tunable filters, termination devices, optical amplifiers, transceivers and add-drop multiplexers are becoming more reliable and affordable. Access networks and metro networks are increasingly being built with optical technologies to overcome electronic blocking at network edges

Laser stands for Stimulated Emission Light Amplification. We all know that light is an electromagnetic wave. Each wave has its own luminosity and color, and vibrates at an angle called polarization. This theory also applies to lasers, but it is more parallel than any other light source. Each part of the beam has almost exactly the same direction, so the beam divergence is small. With a good laser, objects up to 1km away can be illuminated with a spot of light with a radius of about 60mm. Because it's so parallel, it can be focused to a very small diameter, where the concentration of light energy becomes so high that you can pierce, cut, or twist it with a beam of light.

Optical or optical technology refers to anything related to light or vision, whether visible light or infrared light, that performs a specific function. For example, fiber optics, like the one pictured to the right, is a type of wire usually made of glass or plastic that carries light signals. Photonics is the science and technology of generating, controlling and detecting photons, which are particles of light. Photonics underpins the technologies of everyday life, from smartphones and laptops to the internet, medical instruments and lighting technology.

Nano photonics is the study of the behavior of light at the Nano scale and the interaction of Nano scale objects with light. It is a branch of optics, electrical engineering and nanotechnology. These are often metallic components, which can transport and focus light by means of surface Plasmon polarities. Bio photonics can also be described as "the advancement and application of optical techniques, particularly imaging, to the study of biological molecules, tissues and cells".

A quantum sensor is a device that exploits quantum correlations, such as quantum entanglement, to achieve better sensitivity or resolution than using classical systems alone. Quantum sensors can measure the effects of quantum states of AC systems on their own. The simple act of measurement affects the quantum state and changes the probability and uncertainty associated with its state during the measurement. Quantum sensor is a term used in other contexts where entangled quantum systems are bullied to make more sensitive magnetometers or atomic clocks

Optical imaging uses light and the special properties of photons to obtain detailed images of organs, tissues, cells and even molecules. The techniques offer minimal or non-invasive methods of looking inside the body. Optical sensing is a broad class of devices for sensing light intensity. It can be just a simple component to notify when ambient light levels rise above or fall below a prescribed level, or a highly sensitive device to detect single photons. Most optical sensors produce an electrical output.

Astrophysical optics is the branch of optics and photonics that uses light control components to image celestial bodies. Astronomical optics combines precision-machined lenses and mirrors to reduce image distortion, and a high-sensitivity sensor to detect low levels of light. Astrophysics is the branch of space science that applies the laws of physics and chemistry to understand the universe and our place in it. Astronomy measures the position, luminosity, motion, and other properties of celestial bodies. Astrophysics creates physical theories about small and medium-scale objects and structures in the universe.

Fiber optics The use of thin, flexible fibers of glass or plastic as waveguides or “light pipes” to channel light from one place to another. Optical fiber is based on the principle of total internal reflection (TIR). Light enters the fiber at a particular fiber laser in which the laser medium is an optical fiber doped with low levels of rare earth halides to make it capable of amplifying light. The output is adjustable over a wide range and can be broadband. Laser diodes can be used for pumping.

Fiber optic sensors (also known as fiber optic sensors) are fiber-based optical sensors that are subject to a certain amount, usually temperature or mechanical stress, but displacement, vibration, pressure, acceleration, rotation (optical gyroscope based on the Signac effect). Measured with), or the concentration of the chemical species. The general principle of single frequency fiber lasers from super luminescent sources is that they are transmitted over fiber optics and the parameters are subtly changed in one of the fibers of multiple fiber Bragg gratings and these changes are measured. Achieves detector placement.

Quantum Nano science is the area of ​​fundamental research at the intersection of Nano scale science and quantum science that creates the understanding that enables the development of nanotechnology. He uses quantum mechanics to explore and use coherent quantum effects in artificial nanostructures. This could eventually lead to the design of new types of Nano scale devices and materials, where the functionality and structure of quantum Nano devices are described through quantum phenomena such as superposition and entanglement. With the growing work towards realizing quantum computing, quantum has taken on a new meaning that describes effects at this scale. The actual quantum refers to the quantum mechanical phenomena of superposition, entanglement and quantum coherence that are designed in place of natural phenomena.
