$\phi$=$kL$=$\frac{2\pi nL}{\lambda}$

GD: $\frac{d\phi}{dw}$=$\frac{L}{c}(n-\lambda\frac{dn}{d\lambda})$

GDD: $\frac{d^2\phi}{dw^2}$= $\frac{\lambda^3 L}{2\pi c^2}\frac{d^2n}{d\lambda^2}$

TOD:$\frac{d^3\phi}{dw^3}=\frac{\lambda^4 L}{4\pi^2c^3}(3\frac{d^2n}{d\lambda^2}+\lambda\frac{d^3n}{d\lambda^3})$


Input
Refractive index, n :
Light Wavelength, $\lambda$:
nm
Material thickness, L:
mm





Output
GD :
$fs$
GDD :
$fs^2$
TOD :
$fs^3$
