Ultrafast optics is a subpart of optics that deals with the phenomena that occurs on or within picoseconds i.e. ultrafast events. Since such fast events cannot be examined by electronics, optical techniques such as the pump-probe measurements are mandatory. This technique of ultrafast optics had a wide application range including industries, manufacturing, biochemistry and photo dissociation process. Based on the time scales many techniques have been developed such as
Nanophotonics is the optical technology that deals with the interactions of the photons with nano particles including the carbon, nano metals, nano crystalts, and semi-conductors. Whereas Biophotonics is the term which establishes the blend of photonics and biology. This biophotonics is an optical technique that helps to study the biological substances such as cells and tissues present in the body. The main application of the biophotonics is to reserve the cell integrity.
The Photonic Integrated circuit (PIC) can also be termed as the Photonic microcircuit. These circuits are the single assemblage of many optical devices such as amplifiers, Optical lasers, and multiplexers. The main difference between the electrical integrated circuits and photonic integrated circuits is that instead of electrons, PICs utilize photons of light or other electromagnetic radiations. Its fabrication varies depending on the purpose for which it is used. The main application of these photonic integrated circuits includes fibre-optic communication, multiplexers, Biomedical and photonic computing as well as in metrology.

An optical fibre sensor is a sensing instrument that utilises Optical tools for gauging the physical quantities. Some of the physical quantities are pressure, strain, temperature, acceleration, voltage measurement etc. For the sensing purpose they utilise the optical fibres namely intrinsic sensors and extrinsic sensors. These optical fibre sensors are widely used because they have an advantage to monitor extreme conditions and are resistant to electromagnetic interference. Hence they became the sensor of choice for large scale industries.

Green photonics is the branch of photonics dealing with the development of the applicable optical systems for creating a hygienic environmental renewable energy. This field also focuses on saving renewable energy, reducing the levels of greenhouse gases and also producing the light by natural means. Green photonics includes the devices such as solar cells, photovoltaic devices and also constructing environment friendly gadgets including the optoelectronic devices and components.
Terahertz radiation is a part of electromagnetic radiation which lies in the frequency range of 0.1THz to 10HTz and wavelength ranging from 2mm. This radiation is found usually above the radio waves and below the IR frequency. One of the most important applications of this terahertz radiation is the Terahertz imaging technique. This radiation can easily penetrate through the substances such as paper, walls, plastics etc. Hence this imaging technique is widely used in the quality control checks in large scale industries. Since these radiations are stronger than the microwaves the depth of imaging is limited.

SSL is a form of light emission that utilises Light emitting diodes made of semiconductors, Organic light emitting diodes (OLED) or polymer light emitting diodes (PLED) as the sources of illumination rather than the electrical elements. The application of this solid-state lighting is seen in the daily life like traffic lights. They are also used in the vehicle lights, street as well as the parking lights. These lightings can be controlled by non-imaging optics.

Quantum theory was first proposed by a famous physicist Max Planck. Quantum science is an emerging technology related to physics and engineering, which utilises the principles of quantum physics. Some of the examples of the quantum technology involve quantum computing, quantum imaging, quantum sensors and quantum simulation. The basic applications of this quantum technology are involved in the secure connections and quantum computing. The quantum computing plays a major role in the optimization and machine learning.
Optical interchanging systems are gaining more prominence as they are highly essential now. To suit the high ability transport networks the thick wavelength division multiplexing is selected. Optical machineries such as optical intensifiers, tuneable channels, headsets etc. are provided with the drop multiplexers. Metropolitan space systems are designed with the optical advances in such a way that they overcome the limitations of the electronic means. The Optical communications and networking is a key science in the today’s world. This technology supports the applications such as cloud computing and wireless communications.
Optical fibres and photonic devices are widely used in medicine in the form of sensing devices such as MRI and CT scanning for monitoring during the medical imaging. These types of scanning techniques utilises the high intensity electromagnetic radiations for sensing. In the medical field there are some tasks that need fine equipment’s to dissect the body. In such typical conditions appropriate use of lasers can prevent the damages such as blood loss; chances of infection can be reduced provided that proper healing of wound can be seen. Besides all these laser treatment is also indulged in curing eye problems.
Lasers are said to emit light beams of very high intensity. These technologies of the optics and photonics are utilised in the fields of scientific instrumentation, optical engineering, biomedical researches, wireless communications, environmental science, in the fields of medicine. Moreover the laser and the optical technologies are very useful in the fields of medicine for healthy living. They can also be used in the galvanometers and beam splitters.
Nonlinear optics is a field of optics that defines the nature of light beams in the nonlinear means. The non-linearity is the condition which is seen when the polarization density responds nonlinearly to the electrical field. This condition is usually coincided with the very high intensity lights which are emitted by the instruments such as lasers. According to the Schwinger limit the vacuum is considered as the nonlinearity. In the nonlinear optics the principle of superposition is not considered.
The telecommunications industry had been revolutionised with the upcoming of the optical fibre communication. It also played a major role in the development of the data networking community. By using the optical fibres in the communication the distance has increased with the less loss in transmission. Due to the above examples they are employed widely in the broadband distribution systems, data networking and telecommunications.

A photonics mast is also called as optronics mast. It is structurally a sensor that operates on a submarine. This photonics mast is very similar to the periscope hence used as a substitute to it without needing a periscope tube. This mast has many advantages such as it frees up the space required by periscope and thereby limiting the danger of water leakage into submarine. It works by rising above the water like a telescoping car and provides the information through the sensors by using the high definition low light and thermo graphic cameras.
There are many prominent applications related to photonics. They comprise our daily life activities to the most advancement in the science.
