Optoelectronics is a branch of science that studies electronic devices related to light and is also considered a sub-field of photonics . In this context, the light studied also includes all the spectrum of light in electromagnetic waves (electromagnetic spectrum) such as gamma rays, alpha rays, X-rays, ultraviolet and infrared, which are forms of invisible radiation other than the light visible to the normal human eye ( visible spectrum) as well as laser light.In this branch of science, the advantages found in combining the fields of optics and electronics are the ability to produce much better and more useful equipment, especially those related to fiber optic telecommunications technology itself.
