Abstract
A device for transmitting and/or modulating in-phase and quadrature optical signals generated by an optical source. This device includes modulators each arranged for modulating intensity of optical signals depending on commands, and at least three main multi-mode interferometers set in series and arranged for transforming in combination a received optical signal with an initial phase state into a final optical signal with a final phase state differing from this initial phase state by an accumulated phase shift chosen from a group including 0, π/2, π and 3π/2 and depending from the intensity modulations carried out by the modulators.
