Optics, Lasers and Photonics

Geometrical Optics is a type of Optics which could be seen by a phenomenon in which an object is dropped in still water such that circular waves are produced which propagates out of the contact point over the two-dimensional surface. If we consider a light source which emits light in three-dimensional directions, the waves are spherical and direction of the wave front is perpendicular to the wave front.         

It is the technology which involves the electronic device application to the sourcing, detection and control of light. This technology encloses the design, manufacture and study of electronic hardware devices which as a result translates electricity into photon signals. This is being used in many fields like in medical equipment, telecommunications and for general science. Some of the examples are Fibre optic technology for telecommunication and X-ray machines in hospitals.

These are the part of optics which deals with several kinds of optical nonlinearities (nonlinear crystal materials or optical fibres are some examples). This also involves the study of phenomenon which takes place as the consequence of the changes in the optical properties of a material system in the presence of light.

It is the part of physical science which deals with the generation, controlling and detection of light waves and photons using several phenomena’s like generation, detection and manipulation through various processes like transmission, emission, signal processing, modulation, amplification, switching and sensing.

This is the field of physics which involves the study of interactions of electromagnetic radiation or photons with mechanical systems via radiation pressure. It also refers to the manufacturing and maintenance of opto mechanical parts and devices like mirrors mounts, rails, optical mounts, micrometres, screws, screw sets, fibre aligners, rotary and kinetic stages.            

Nano Optics is the study of materials and their structures at a very small (Nano) level which would help in giving an idea about the properties of the material and sometimes it’s structural representation in a very clear manner. These Nano sized structures were already existed before scientists have studied about the in the real life at their laboratories. Some of the live examples of these Nano materials would be DNA, scales of the wings of butterflies and peacock feathers.

Optical Communication is a type of communication in which the information from one place to another is being transmitted through light which carries the information. This phenomenon can be seen in the electronic devices. The whole system consists of a transmitter and a receiver where the transmitter transmits the information in the form of optical signal by encoding the message. This signal will be carried till the destination thus; the receiver will receive it and decodes it in the form of the actual message. Whereas optical networking is same as optical communication but the only difference is that the transmitted information will be sent among the various nodes of telecommunications network.

Optics is being used as a crucial part in the field of medicines such that from the manufacturing of medicines to the treatments of patients. Many instruments have been developed since nineteenth century.  

Lasers and Photonics are being  used for many uses which involves different fields for instance we consider defence, hospitals, manufacturing unit and etc. where these technologies are being used in order to do several activities like welding, laser treatment, cutting respectively. These are source of energy which consists of extra ordinary properties. This process involves the usage of highly powered lasers.
