Figure 2. SOAs optical characterization.

Figure 2

a, extinction efficiency spectra of SOAs for varying light incidence angles. b,c, 2-D plots simulated, in resonance condition (700 nm), on a plane that passes through the center of the system, perpendicular to the SOA short axis: respectively normalized electric field distribution and charge density distribution. d,e, normalized electric field distributions respectively of the β and α resonances for θ = 50°. f-h, respectively extinction (Qext), scattering (Qscatt) and absorption (Qabs) efficiencies of SOAs in correspondence of the peak around 700 nm, as a function of the light incidence angles.
