try with this, assuming that the units don't need conversion :

syms t

mu=200; %cm^2*V^-1 * s^-1

R = 0.318;

alpha= 6000; %cm^-1

taul= 100; %fs

tauc= 1; %ps

W=10; %micro m

L=10; %micro m

Tlt=1 %micro m

V=30; %V

vopt=375 %THz

g= (W/L) * exp(1)*mu*I*exp(-2) *(1-R)*(1-exp(alpha*Tlt))*(sqrt(2*pi)/4*h*vopt)*taul*exp((-taul^2)/(8*tauc^2) -t/tauc)* erf((sqrt(2)*t/taul - sqrt(2)*taul/(4*tauc))+1)

note that i think im missing a value for I and h that are not in the input parameters given

syms t

mu=200; %cm^2*V^-1 * s^-1

R = 0.318;

pi=3.14;

alpha= 6000; %cm^-1

taul= 100; %fs

tauc= 1; %ps

W=10; %micro m

L=10; %micro m

Tlt=1 %micro m

V=30; %V

vopt=375 %THz

e=1.602*(10^-19);

t=linspace(-300*(10^-15),300*(10^-15),100);

h=6.626.*(10.^-34);

I=1.052.*(10.^15);

g=(W/L).*e.*mu.*I.*exp(-2).*(1-R).*(1-exp(alpha.*Tlt)).*(sqrt(2.*pi)/4.*h.*vopt).*taul.*exp((-taul.^2)/(8.*tauc.^2)-t/tauc).*erf((sqrt(2).*t/taul-sqrt(2).*taul/(4.*tauc))+1)

plot(g,t)

Is this correct?
