SOA

Semiconductor Optical Amplifier

I have used the Rung-Kutta 4-order numerical method for the simulation of the Linear SOA for the first time. This code is simple and light but can teach the basis of SOA to students.

I have shown the results and explanation in the following book:

Variables:

• t0 : initial time (starting time)

• H0 : initial condition (H(t0))

• h : simulation steps

• tp : FWHM

• tauc : carrier recovery time

• alfa : linewidth enhancement factor

• ein : input energy

• L : length of SOA

• g0 : linear gain(1/m)

• h0 : unsaturated gain

• iter : iteration
