$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
in each ddcc layer. Ideally, the cavity can be calculated by
.
Effective absorption loss can be calculated by
.
By the formula, can know that to obtain the gain
.
The $cavitygainedge setting for 1D-DDCC in GUI interface
The parameters are modified in Step 3.
