Cavity Solitons in VCSEL Devices

Figure 12

(a) Drift speed versus phase gradient (wave-vector tilt of holding beam) for a scaled cavity photon to carrier recombination rate 𝛾=0.01 (corresponding to a nonradiative carrier lifetime of 1ns⁻¹) and two-cavity detuning values. The cavity photon lifetime is 10 ps. (b) Log-log plot of CS drift speed versus 𝛾 for a fixed scaled detuning (𝜃=−2) and for two values of the gradient: (stars) 𝐾=2.38×10⁴m⁻¹; (diamonds) 𝐾=1.91×10⁵m⁻¹. Here, the cavity photon lifetime is 1.5 ps. Figure reproduced from [110].
