This dataset contains simulation and experimental data presented in the paper titled 'Ultrafast switch-on dynamics of frequency tuneable semiconductor lasers'

Fig_1a.xlsx contains experimentally recorded and processed spectra when the laser cavity was driven with an amplitude of 0.75A and the amplitude of the current pulses supplied to the tuning cavity was varied (at a heat sink temperature of 5K). Side mode suppression ratio (processed from experimentally recorded spectra) at two discrete emission frequencies for tuning current amplitudes of 0A and 1.97A are also included. This data corresponds to Fig. 1(a) of the paper.


Fig_1b.xlsx contains side mode suppression ratio and output power of modes at 2.825THz and 2.765THz (processed from experimentally recorded spectra) as a function of tuning current amplitudes. This data corresponds to Fig. 1(b) of the paper.


Fig_1c.xlsx contains data from simulation of the steady-state emission spectrum of the coupled-cavity laser for different current amplitudes supplied to the tuning section, calculated using a transfer matrix model. This data corresponds to Fig. 1(c) of the paper.


Fig_3a.xlsx contains experimentally recorded electric field emitted from the output facet of the tuning cavity, measured as a function of time, when the lasing cavity is driven using quasi-direct current pulses of amplitude 0.65 A and the tuning cavity is switched off. This data corresponds to Fig. 3(a) of the paper.


Fig_3b.xlsx contains temporal dynamic variation of the emission spectra (processed from experimentally recorded time-domain electric field) using a moving time window of width 150ps. This data corresponds to Fig. 3(b) of the paper.


Fig_3c.xlsx contains processed spectra obtained from fast Fourier transform of the time-domain electric field using a time window of width ~460ps beginning at t=400ps and 1700ps. This data corresponds to Fig. 3(c) of the paper.

Fig_4a.xlsx contains experimentally recorded distribution of power amongst lasing modes at 2.795, 2.825 and 2.855THz, as a function of cavity round-trips. This data corresponds to Fig. 4(a) of the paper.

Fig_4b.xlsx contains data from simulation of changes in distribution of power amongst lasing modes at 2.795, 2.825 and 2.855THz, as a function of cavity round-trips. This data corresponds to Fig. 4(b) of the paper.

Fig_5a.xlsx contains experimentally recorded electric field emitted from the output facet of the tuning cavity, measured as a function of time, when the lasing cavity is driven using quasi-direct current pulses of amplitude 0.65 A and at different current pulse amplitudes at the tuning cavity. This data corresponds to Fig. 5(a) of the paper.


Fig_5b.xlsx contains data from simulation of comb alignment at frequencies 2.765THz and 2.825THz, as a function of current pulse amplitudes at the tuning cavity. This data corresponds to Fig. 5(b) of the paper.

Fig_5c.xlsx contains experimentally measured switch-on delay and simulated laser stabilisation time, as a function of current pulse amplitudes at the tuning cavity. This data corresponds to Fig. 5(c) of the paper.
