Method and device for converting a digital signal into optical pulses

摘要

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.

主权项

1. A method for converting a digital signal into optical pulses, comprising the steps:
separating an optical signal into three intermediary beams, phase-shifting the three intermediary beams by an angle of about 2π/3 from one another, and selecting at least one of the intermediary beams for creating optical pulses coding the digital signal.
