Abstract:
A method for handling an optical pulse signal in a communication fiber link by ensuring at least one operation from the following: pulse shaping, treatment of nonlinearity and monitoring, the method comprising:providing a signal handling device comprising one or more SHG elements, each being capable of performing a cascaded second harmonic generation (SHG) with respect to a particular fundamental harmonic (FH), selecting at least one of said operations, selecting an inner optical path length in said one or more SHG elements to perform said at least one selected operation with respect to an incoming optical pulse signal carried by a wavelength defined by said particular fundamental harmonic (FH), conveying the incoming optical pulse signal carried by said wavelength along the selected optical path in said signal handling device, according to the selected at least one operation, obtaining from said signal handling device at least one output optical pulse signal from a list comprising: an output optical pulse signal at the fundamental harmonic (FH), wherein the treatment of nonlinearity and/or the pulse shaping are performed, an output optical pulse signal at the second harmonic (SH) for further monitoring it and judging about said input optical pulse signal.
