$activateStimEL is a command used to enable the calculation of stimulate Emission.

The stimulate emission coefficient is calculated by:

B_{stim} = B_{0} \times \beta \times \frac{R_{rad}}{R_{th}-R_{rad}}
R_{stim} = B_{stim} \times n \times p 
 B_{0}:  is the radiative recombination coefficient
 R_{th}: is the threshold recombination rate
 R_{rad}:  is the spontaneous radiative recombination rates decided by   B_{0}\times n \times p 
 \beta:  is the fitting coefficient. 

The way to activate the command is as following

$activateStimEL
Method QW_number 1st_QW_layerNum 2nd_QW_layerNum 3rd_QW_layerNum ...
 \beta_{1}  R_{th,1}  , P3_1, P4_1
 \beta_{2}  R_{th,2}  , P3_2, P4_2
 \beta_{3}  R_{th,3}  , P3_3, P4_3
 \beta_{4}  R_{th,4}  , P3_4, P4_4
 \beta_{5}  R_{th,5}  , P3_5, P4_5
.....
..... total N layers (regions)
 \beta_{N}  R_{th,N}  , P3_N, P4_N
Method: 1 -> Given  \beta and R_{th}  of each layer. If this is layer is not QW, set  \beta=0.0  R_{th}=0.0 
Method: 2 -> defined for future expansion
P3, P4 : Not used, may be used when Method 2 is activate in the future


For example:

$activateStimEL
1 1 2 
0.000 5.0e27 0.00 0.00
1.000d-4 5.0e27 0.00 0.00
0.000 5.0e27 0.00 0.00
0.000 5.0e27 0.00 0.00

In this command, use method 1. There is 1 QW which is the 2nd layer. The  \beta and R_{th} of the 2nd layer is 1.0e-4 and 5.0e27  (1/cm^{3}s)
