In this paper, for the first time a circuit model of quantum dot InGaAs-GaAs VCSEL including thermal effects is presented. The model is able to predict L-I characteristics for a range of ambient temperatures that the simulation results reveal a good agreement with experimental data reported in literatures. Also the effects of carrier dynamics on the QD-VCSEL performance are simulated that is accordance with results reported by other researcher. The parameters affecting high-speed optical modulation techniques, particularly on-off keying, such as turn-on delay, relaxation oscillations frequency (f ro ) and cutoff frequency for different level modulation currents are investigated. The model is compatible with circuit analysis programs.

“…The internal quantum efficiency comprises two physical effects: the carrier diffusion in the active volume and the carrier leakage out of the QWs due to thermionic emission. 33 While the carrier diffusion is mainly a function of the driving current, the carrier leakage is mainly a function of the internal temperature. Figure 9͑a͒ shows that plotting the values of the internal quantum efficiency results almost in a single curve.…”

Tradeoffs of vertical-cavity surface emitting lasers modeling for the development of driver circuits in short distance optical links

et al. 2005

In short-distance optical links, the development of driving circuits for vertical-cavity surface-emitting lasers ͑VCSELs͒ requires precise and computationally efficient VCSEL models. A small-signal model of a VCSEL is computationally efficient and simple to implement; however, it does not take into account the nonlinear output behavior of the VCSEL. In contrast, VCSEL models that are highly based on first principles cannot be implemented in standard circuit device simulators, because the simulation of eye diagrams becomes too time consuming. We present another approach using VCSEL models, which are based on the 1-D rate equations. Our analysis shows that they combine efficient extraction and short simulation time with an accurate calculation of eye diagrams over a wide range of ambient temperatures. As different implementations of the rate equations exist, tradeoffs between three different versions are presented and compared with measured GaAs oxideconfined VCSELs. The first model has a linear and the second a logarithmic function of the gain versus the carrier density. The third model considers the additional transport time for carriers to reach the active region with quantum wells. For parameter extraction, a minimum set of parameters is identified, which can be determined from fundamental measurements.

“…The increasing in temperature causes the increase the threshold current density, plus reduce the output power, and shift frequency to longer wavelength, in addition, it may reduce its lifetime. D. Botez [24] and S.Fu [25] indicate the steady state thermal rate equation inside cavity of VCSELs as following: [24], S.Fu [25] and N.Bertra [26] did an excellent work on single VCSEL thermal analysis. They tried to extend the work through arrays of VCSEL using finite difference method and finite element method, however, the heat distribution on VCSELs array was difficult to estimate through those numerical methods.…”

-Many research papers on optical interconnects have been published over the last three decades, however, some models are oversimplified and overlooked important design considerations. These include the timing synchronization of the VCSEL sources; detailed calculations of the free space optoelectronic interconnect network, theoretical analysis of computer generated hologram on optical interconnect system. An example of detailed analysis are presenting here for devising optoelectronic interconnect switching network based on a banyan switch. In order to expand the work into a large optoelectronic switching arrays, more careful considerations may be necessary from system perspective..
