Single pulse (pulsewidth = 30ps, Max power = 10mW) traveling throught SOA

Описание: SOA refractive index = 3
SOA width = 1.5um
SOA height = 0.3mm
SOA length = 0.5um
SOA transit time = (0.5um/3e+8)*3 = 5ps
Number of slices = 100
transit time of each slice = 50fs
time step (delta t) = 50fs
The whole span of the pulse train = 100ps
number of operation (gain, Pout, Phase_out) in each slice = 100ps/50fs = 2000
total number of operation = 2000 per slice * 100 slice = 200 000

Unsaturated gain g_0 = 13815.51 / Go=30dB
interband carrier lifetime = 75ps
interband carrier recovery time (10% - 90% ) ~=100ps
No intraband carrier transition
Injection current = 300mA

Pulseshape = Gaussian
Pulsewidth (FWHM) = 30ps
Peak Power = 0.01W
Center wavelength = 1.55um
Gain coefficient = (3*(10^(-20))m^2)
Linewidth enhancement factor = 5 (constant)
Confinement factor = 0.3
sigma = Width*height/carrier lifetime
E_sat = h*c*sigma/(lamda*a)= 6.4123pJ
