So, as the lifespan of the atom expires it now comes back to ground level from the higher energy level. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core of singlemode fibers. This radiation emission phenomenon is usually seen in optoelectronic devices such as LED. Thus, an electromagnetic wave of frequency ν is provided to the atom at the ground level. Ein Diodenlaser arbeitet nach demselben Prinzip wie eine Leuchtdiode (LED). The crystal is doped to produce an n-type region and a p-type region, one above the other, resulting in a p-n junction, or diode..
