Low-energy switch based on a cavity soliton laser

Spatiotemporal extreme events in a laser with a saturable absorber

“…Time is scaled to the photon lifetime (≈ 10 ps) and space is scaled to the diffraction length (≈ 4 µm). For a more detailed definition of all these parameters see [8].…”

“…Here we show numerical results about extreme events occurring in the field intensity emitted by a monolithic broad-area VCSEL with an intra-cavity saturable absorber [5][6][7][8][9], as the one used in the experiments on cavity solitons [4,10].…”

Periodic and chaotic solitons in a semiconductor laser with saturable absorber

“…The coefficients B 1 and B 2 are the rates of radiative recombination. For a precise definition of all variables and parameters, see the appendix of Vahed et al [10].…”

“…Here, we take into account the effects of carrier recombination and consider the parameter set B 1 = B 2 = 0.1, s = 1, γ = 2, α = 2, β = 1, b = 0.01 and r = 1 [10,28,29,[31][32][33]. For this set of parameters, the stationary CSs are stable for a wide range of pump current values μ (see fig.…”

“…Under this respect, the functionalities of CSs are enhanced if they can move in the transverse plane, oscillate at fixed position or even oscillate while they move. For instance, the mobility of CSs under an external control beam was used to implement an all-optical delay line [9] and a low-energy optical switch [10].…”
