The Photonics industry refers to all related industries of materials, parts, instruments and systems which make, control and apply the light.
The Photonics industry is normally divided as follows: optical communication (Fiber Optics, Optical connector), Optical Material, Optical application (LED, Solar Energy), Optical Information (Optical diode, Laser Machining), and Optical Precision (Optical Sensor etc)
While the 20th century was the age of electron, the 21st century is that of photon.
Photonics intustry is technology-intensive advanced industry and has a great pervasive effect on related industries(information and communication areas). It is also applied to the various areas such as medical service and energy.
Photonics industry is an intensive information industry that could solve environmental problems without depending on natural resources and energy. Therefore, it has the potential of continuous high growth.
Since its product cycle is short, the creation of a new technology and investment should be continuously done.
Comparably high Value Added Ratio of 35 ~ 45% (Average Value Added Ratio of Small and Medium companies in Manufacturing industry is 22% in 2000, Business analysis, 2000, Bank of Korea)
i.e., Photonics is an environmental friendly and developed country type industry.
