Optics: gain/absorption calculation

Dielectric constants

The bulk permittivity is calculated from the following relation (Lyddane–Sachs–Teller relation):

$$ \epsilon_{\text{bulk}}(\omega) = \epsilon_{\infty} + (\epsilon_0-\epsilon_{\infty}) \frac{\omega_{\text{TO}}}{\omega^2_{\text{TO}}-\omega^2}$$
