<s>[INST] 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 ? [/INST] 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[i*10+j, i*10+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.</s>\ <s>[INST] Please repeat that with better formatting. [/INST]
