Abstract
To that end, it is an object of the invention to provide a method for converting a high-speed digital signal in the form of optical pulses intended to be transmitted within optical guides, within which the signal is converted into a series of optical pulses in three possible phase states (π/6, 5π/6, −π/2) separated from one another two-by-two by an angle greater than π/2.
