WebAug 1, 1998 · The effect of intensity distortion induced by cross-phase modulation in dispersive optical fibers is studied. It is shown that, in most configurations in which distortions that are due to cross-phase modulation can become significant to optical communications, the effect of cross-phase modulation can be described with excellent …

Slew-induced distortion (SID) can produce intermodulation distortion (IMD) when the first signal is slewing (changing voltage) at the limit of the amplifier's power bandwidth product. This induces an effective reduction in gain, partially amplitude-modulating the second signal. If SID only occurs for a portion of the signal, it is called "transient" intermodulation distortion. WebWideband photonic links suffer not only from the traditional intermodulation distortions (IMD) but also from the cross modulation distortions (XMD) caused by the out-of-band signals, which severely limit the dynamic range of the links. In this paper, we propose and experimentally demonstrate a novel scheme to effectively suppress the cross …

WebIntermodulation distortion is defined as the production of new output signals which are created from the nonlinear combination of two or more input signals. This intermodulation occurs because of the nonlinearity in the amplification process.
