The subwavelength domain can be applied to optical switches, modulators, photodetectors, and directional light emitters.

Organic electronics not only includes organic semiconductors, but also organic dielectrics, conductors and light emitters.

Despite the wide numbers of metal ion donors, they serve to form only a few atomic and molecular species that are useful as light emitters.

Another reason is that the light emitter was actually quite a distance from the lens.

"The photodetectors are only a centimeter or so in diameter, and the light emitters are maybe ten times that size."

The second distance "m" between the two clusters of light emitters in the Sensor Bar is a fixed distance.

Power recycle indicator - A light or sound emitter or both which tell the photographer that the flash has fired, and is currently charging.

Quantum dots incorporate the best aspects of both organic light emitters and inorganic light emitters.

This turns the model from a light radiator to a light emitter.

One issue with using silicon for an optical device is that silicon is a poor light emitter and cannot be used to make an electrically pumped laser.
