Hi there, for the purpose of explaining the process of a bi-dimensional wavelength/time encoding in OCDMA systems using a comprehensive illustration, I would like a simple Latex code, Python or MATLAB script for plotting a 3D figure of encoded pulses. The wavelength, time, and intensity are represented by the axes of the graph and the pulses are spread within the wavelength/time space using a unipolar encoding scheme. Would you be able to provide the code for such an illustration ?

Certainly! Here is an example Python script that creates a 3D plot of encoded pulses with wavelength, time, and intensity as the axes:
python Copy code import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D
Define the wavelength and time axes
wavelengths = np.linspace(1500, 1600, 101) times = np.linspace(0, 100, 101)
Create a 2D array to represent the encoded pulses
pulses = np.zeros((101, 101))
Encode the pulses using a unipolar encoding scheme
for i in range(10): for j in range(10): pulses[i10+j, i10+j] = 1
Create a 3D plot of the encoded pulses
fig = plt.figure() ax = fig.add_subplot(111, projection='3d') X, Y = np.meshgrid(wavelengths, times) ax.plot_surface(X, Y, pulses, cmap='viridis') ax.set_xlabel('Wavelength (nm)') ax.set_ylabel('Time (ns)') ax.set_zlabel('Intensity') plt.show() This script creates a 3D plot of encoded pulses with wavelength ranging from 1500 nm to 1600 nm and time ranging from 0 ns to 100 ns. The encoded pulses are spread within the wavelength/time space using a unipolar encoding scheme, where each pulse is represented by a spike in intensity at a particular wavelength and time. The resulting plot shows the pulses as a series of peaks within the wavelength/time space.
You can modify the script to change the range and resolution of the wavelength and time axes, as well as the encoding scheme used to create the pulses.

Please repeat that with better formatting.
