#289 Light emission and detection - it is (almost) all semiconductors

The emission and detection of light across the wavelengths range from far infrared to deep UV is these days an integral component of technical infrastructure through which we interact with the world.

 

Both light emission, based on the conversion of the electrical signal into light and light detection, in which case conversion of light into electricity is taking place, are based almost solely on semiconductor devices. Whether these are for instance light emitting diodes (LEDs) or image sensors such as CCDs (charged coupled devices) both emission and detection of light is based on the unique physical properties of devices constructed using semiconductor materials.

 

On more than one occasion I was surprised to see that this obvious fact is not all that obvious to some people...
