it may requre more informationbut you may use the following code

% Define parameters
f = 10e9; % Electrical signal frequency
T = 1/f; % Period of electrical signal
n = 2; % Refractive index of modulator
L = 1e-3; % Length of modulator
Vpi = 5; % Half-wave voltage of modulator
Vbias = 2; % Bias voltage of modulator
alpha = 0.1; % Modulation depth
% Generate electrical data
t = linspace(0, 10*T, 1000);
data = sin(2*pi*f*t);
% Convert electrical data to optical
phi = pi*alpha*data;
E1 = sqrt(1 - alpha^2)*exp(1i*2*pi*f*t);
E2 = sqrt(alpha^2)*exp(1i*(2*pi*f*t + phi));
Eout = E1 + E2;
% Plot electrical and optical data
figure;
subplot(2,1,1);
plot(t, data);
xlabel('Time (s)');
ylabel('Amplitude');
title('Electrical Data');
subplot(2,1,2);
plot(t, abs(Eout).^2);
xlabel('Time (s)');
ylabel('Power');
title('Optical Data');

% Calculate modulator transfer function
V = linspace(-Vpi, Vpi, 100);
T = cos(pi*V/Vpi).^2;
% Plot modulator transfer function
figure;
plot(V, T);
xlabel('Voltage (V)');
ylabel('Transmittance');
