Optics and Photonics: What is it?

In summary, optics can be described as the branch of physics and engineering that studies and utilizes the properties of light, from classical optics to quantum optics. Photonics, on the other hand, can be seen as a sub-field of optics that focuses on engineering applications, such as fiber optics and optical processing, and is closely tied to electronics through the use of semiconductor materials and devices.

I have a pretty good idea on the basics of optics and photonics but I am hoping that someone here has some indepth knowledge about the particulars of these fields.

What is the core of these fields? Meaning, if you had to descibe the optics field in one paragraph, same with photonics, what would you say about it to really portray what it is as a whole?

Definitions may vary, but I would define the field of optics as the entire branch of physics and engineering that investigates and exploits the properties of light. Optics is a sub-field of physics, but it also includes optical engineering that cannot be classified under pure physics. It would cover everything from classical optics (lenses, mirrors, etc.) to theoretical quantum optics. As a result, I would classify photonics as a sub-field of optics just like electronics is a sub-field of engineering.

Here is quote from the preface in "Fundamentals of Photonics" by Saleh and Teich:

In recent years, the term photonics has come into use. This term, which was coined in analogy with electronics, reflects the growing tie between optics and electronics forged by the increasing role that semiconductor materials and devices play in optical systems.

I would also say that photonics is a more engineering oriented approach to optics. It includes fiber optics, optical processing, and the like.

Optics and photonics are closely related fields that deal with the study and manipulation of light. Optics is the branch of physics that focuses on the behavior and properties of light, including its interactions with matter. It encompasses topics such as reflection, refraction, diffraction, and the formation of images. On the other hand, photonics is a more specialized field that deals with the use and control of light for practical applications. It involves the generation, detection, and transmission of light through various materials and devices, such as lasers, optical fibers, and photonic crystals.

At their core, both optics and photonics are concerned with understanding and harnessing the properties of light to advance technology and improve our understanding of the world around us. They have numerous applications in fields such as telecommunications, medicine, manufacturing, and astronomy. From developing new materials and devices to improving existing technologies, optics and photonics play a crucial role in shaping our modern world. They continue to be areas of active research and innovation, driving advancements in science and technology.
