摘要： An optical communication signal converter (10) comprising:
an input (12) arranged to receive an input optical communication signal (14), having a first wavelength and a first optical power, carrying communications traffic encoded as an intensity modulation;
a non-linear optical medium (18) having a gain spectrum comprising the first wavelength and having a saturation power, and arranged to receive the input signal (14), the first optical power being higher than the saturation power, and arranged to receive a carrier optical signal (20) having a second wavelength, longer than the first wavelength and outside the gain spectrum, , wherein when the carrier optical signal and the input optical communication signal co-propagate in the non-linear optical medium cross-phase modulation of the carrier signal (20) by the input signal causes the input signal intensity modulation to be converted into a phase modulation of the carrier signal, forming an output phase modulated optical communication signal (22) carrying said communications traffic; and
an optical output (24).

摘要： A method for performing optical constellation conversion, according to which each received symbol from a constellation of input symbols is optically split into M components and each component is multiplied by a first predetermined different complex weighing factor, to achieve M firstly weighted components with different amplitudes. Then a nonlinear processor optically performs a nonlinear transform on each M firstly weighted components, so as to obtain M outputs which are linearly independent, Finally, a linear processor optically performs a linear transform to obtain a new converted constellation by optically multiplying, in the complex plane, each of the M outputs by a second predetermined different complex weighing factor, to achieve M secondly weighted components and then summing the M secondly weighted components.
