Numerical modeling and experimental testing of reflective semiconductor optical amplifier (RSOA) with modulation bandwidth optimization
A numerical model for RSOA including spatial variations of carrier density and ASE noise, is established and validated via experimental tests. Performance of RSOA with different cross-sectional areas of active region is investigated in the simulations. Reducing the cross-sectional area can increase its modulation bandwidth.
