$cavitygainedge command is used to help to calculate the cavity gain in the end of gain calculation.
The input format is

$cavitygainedge
R1  R2  cavity-Length

After obtaining the intrinsic gain of laser diode structure. The program calculate the optical mode and also calculate the
$Γ$ in each ddcc layer. Ideally, the cavity can be calculated by

 $g_{c a v} = \sum Γ_{Q W} \times g a i n$ .

Effective absorption loss can be calculated by

 $α_{e f f} = Γ_{i, l o s s l a y e r} \times α_{i}$ .

By the formula, can know that to obtain the gain

 $g_{c a v} > α_{e f f} - \frac{1}{2 L} \times l n (R 1 \times R 2)$ .
