$eigencalEl

$eigencalEl is the command to calculate the emission spectrum. It will calculate the electron and hole overlap, electron and hole eigen values , using Fermi-golden rules to calculate the emission spectrum.

$R(\hbar\omega) =$

The format is

$eigencalEl 
@EPP  @n_r  @sigma

@EPP (eV) is the momentum matrix element transition energy.
@n_r is the refractive index of this material (active region)
@sigma (eV) is the gaussian broadening factor $\sigma$

Example

 $eigencalEl 
 21.0 2.3 0.015
