<emphasis role="bold">Introduction</emphasis> Information can be carried by an optical beam only if the beam is modulated. There are many ways to modulate the laser emission: output wavelength, frequency, intensity, etc. Intensity modulation is used most often because it is well adapted to digital communications and relatively simple to implement. The two forms of intensity modulation are external modulation and internal modulation. External modulation can be achieved by a mechanical whe…
