Abstract
The invention relates to a system (EM, RE) for the optical transmission of a binary code. The invention makes it possible to carry out a coding of the bits transmitted in terms of intensity and phase by choosing a first base in which the signals coding the bits are distinguished only by a first physical quantity, and a second base in which the signals coding the bits are distinguished only by a second physical quantity.
