Abstract
A laser is biased in the vicinity of the bend in its characteristic curve. It also receives, in electrical form, a base wave applied to an input of the generator and a local wave provided by a local oscillator, and it mixes these waves by adding their frequencies so as to modulate the lightwave that it emits. The invention is particularly applicable to telecommunications systems.
