Electro-optics involving components, devices (e.g. Lasers, LEDs, waveguides etc.) and systems which operate by the propagation and interaction of light with various tailored materials. It is essentially the same as often described today as photonics and concerns the interaction between the electromagnetic (optical) and the electrical (electronic) states of materials. A key component in studying electro-optics is understanding the basics of electromagnetism. Texts in the physics library focusing on electromaganetism complement the texts in this area.
