Abstract:
A method for reducing a tilt of a spectrum of light transmitted via an optical fiber, the method comprising:a) providing a source of light; b) connecting the source to a receiver of light via an optical fiber, wherein light populating a set of channels in the C- band and the L-band that is sent from the source to the receiver via the fiber has a first power spectrum at the receiver having a first tilt with a first sign; c) connecting at least one of the source, receiver, and fiber with an amplifier that is configured to produce a gain spectrum with a second tilt that has a second sign that is opposite to the first sign; and d) allowing a packet of light, populating the set of channels and travelling from the source to the receiver, to pass the amplifier, resulting in a second power spectrum of the packet of light at the receiver that has a residual tilt whose magnitude is smaller than a magnitude of the first tilt.
