Functions Used
sum - Summation or sigma (∑) notation is a method used to write out a long sum in a concise way., sum(i, from, to, expr)
Variables Used
Phase Shift Jth Channel - (Measured in Radian) - Phase Shift Jth Channel refers to the change in the phase of the optical signal in the "jth channel" induced by the presence of another optical signal.
Non Linear Parameter - (Measured in Decibel per Meter) - Non Linear Parameter refers to the attenuation coefficient or attenuation rate of optical fibers.
Effective Interaction Length - (Measured in Meter) - Effective Interaction Length used to describe the distance over which light can interact with or propagate through the fiber before certain optical effects become significant.
Power of Jth signal - (Measured in Watt) - Power of Jth signal denotes the power of the "j-th" signal, which could be any optical signal in the system.
Range of Other Channels Except J - Range of Other Channels Except J is the specific range for m is determined by the number of optical channels being considered in the analysis of XPM.
Power of Mth signal - (Measured in Watt) - Power of Mth signal denotes the power of the "m-th" signal, which is another optical signal propagating concurrently with the Pj signal.

What is Cross-Phase Modulation?

Cross-phase modulation (XPM) is a nonlinear optical phenomenon occurring in fiber optic communication systems. It results from the interaction between different optical signals (channels) propagating through the same fiber, the intensity of one optical signal (the pump or modulating signal) induces changes in the refractive index of the fiber, which modulates the phase of another optical signal (the probe or modulated signal). This modulation can lead to various effects, including phase shifts, frequency shifts, signal distortion, and the generation of new optical frequencies through nonlinear mixing processes.

How to Calculate Phase Shift of Jth Channel?

Phase Shift of Jth Channel calculator uses Phase Shift Jth Channel = Non Linear Parameter*Effective Interaction Length*(Power of Jth signal+2*sum(x,1,Range of Other Channels Except J,Power of Mth signal)) to calculate the Phase Shift Jth Channel, The Phase Shift of Jth Channel occurs when two or more optical channels are transmitted simultaneously inside an optical fiber using the WDM technique. In such systems, the nonlinear phase shift for a specific channel depends not only on the power of that channel but also on the power of other channels.
