Optoelectronics

Optoelectronics is the study and application of electronic devices that source, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation.Electro-optics is often erroneously used as a synonym, but is in fact a wider branch of physics that deals with all interactions between light and electric fields, whether or not they form part of an electronic device.

Optoelectronics is based on the quantum mechanical effects of light on semiconducting materials, sometimes in the presence of electric fields.

[News] ASUS readying touchscreen Eee PC and laptops for 2009 Windows 7 launch?
Filed under: Laptops With HP's touchscreen laptop looming on the horizon, out come the leaks of an ASUS touchscreen lappie scheduled for launch in the first half of 2009. Touchscreen Eee PCs too ( finally , right?) if DigiTimes ' sources at panel makers are correct (which they tend to be with regard to ASUS). According to the Taiwanese industry rag, ASUS will likely use either a ...
