“…22 Inclusion of multiple round-trip terms in the field equation would most probably yield a better quantitative agreement with experiments, since it adds correction factors to the gain and frequency of the steadystate, external-cavity modes. 23,24 However our results show that both types of LFF are complementary and co-exist in the same model [Eqs. (1)- (4)] using a single round-trip term in the external cavity as in the LangKobayashi approximation.…”

A numerical study of vertical-cavity surface-emitting lasers with optical feedback demonstrates the existence of two different types of low-frequency fluctuations (LFFs). The competition of two equally dominant polarization modes characterizes one type of LFF, while the other type is characterized by power drops in a dominant polarization mode and power bursts in the orthogonal depressed mode. We characterize and compare these two types of LFFs on the basis of their polarization properties and their dependency on the laser parameters. We show furthermore that a transition is possible from one type of LFF to the other, depending on the values of the linear anisotropies of the vertical-cavity surface-emitting laser cavity.

“…Reference [9]) are well suited for such an application and can readily be extended to include the lateral distribution of both the optical field and the carrier density. Such extended rate equations have already been extensively used for simulation of various dynamic effects in VCSEL cavities, like transverse mode competition [10], mode partition noise [11], modulation response [12], harmonic distortions [13], external reflections [14], or polarization dynamics [15].…”

SUMMARYWe propose a new set of equations describing a cylindrical vertical cavity surface emitting laser (VCSEL) cavity under CW operation, based on the rate equations including lateral carrier diffusion. The only numerical step in the calculation consists in finding the roots of a polynomial expression. This model enables a quasi-instantaneous calculation of the laser's light-current characteristic, including such effects as spatial hole burning, current spreading, inhomogeneous optical intensity distribution, and diffusion losses. An analysis of the VCSELs threshold current and differential quantum efficiency is proposed, which illustrates the interplay between injected current profile and diffusion coefficient.

“…Following the References [5,6,[18][19][20] we have simplified the numerical simulation by assuming the azimuth symmetry dependence of the modes with m > 0 can be neglected when the modes are degenerate. Explicitly, we analyse the case of the competition between two modes LP 01 and LP 11 ; we shall identify the first mode ðc 01 ðr; fÞ ¼ c 1 ðrÞÞ with the index i ¼ 1 and the LP 11 mode ðc 11 ðr; fÞ ¼ c 2 ðrÞÞ with the index i ¼ 2:…”

SUMMARYWe investigate the transverse mode dynamics of weakly index-guided vertical-cavity surface-emitting lasers (VCSEL). The turn-on time of transverse modes are calculated by implementing a model for the VCSEL dynamics including diffusion and transport/capture phenomena. It takes into account the spatial dependence of the two carrier density profiles associated with the confined carriers in the quantum wells, and with the unconfined carriers in the barrier region. Devices of different aperture diameter under different excitation conditions are also studied. The model displays the correct turn-on time dependence on the injection current density when compared with the experimental data available. We show that the turnon time of the modes increases when capture time increases and escape time decreases and also when diffusion increases.
