“…In order to obtain characteristics of electrically pumped VCSELs, we have integrated our previously developed electrical-thermal (ET), gain, and optical modules into a 3D self-consistent ETO simulation tool [Osiński 2001]. The following brief discussion summarizes the main features of these modules.…”

“…In this paper, we apply the ETO simulator to a top-emitting oxide-confined mesa structure. Other configurations, such as bottom-emitting or intracavity-contacted VCSELs, can also be treated, as illustrated in ], , [Osiński 2001]. …”

“…Many approaches to that problem, different in terms of their completeness, generality, accuracy, complexity, and efficiency, have been made [Thode 1994], [Hadley 1996], [Tsigopoulos 1997], [Klein 1998], , [Gustavsson 2002] (to mention just the few that try to tackle the problem in its entirety), with none of them, as of now, having won general acceptance. In this paper, we employ our self-consistent electrical-thermal-optical (ETO) model used previously for design of widebandgap nitride VCSELs [Osiński 2001] to investigate properties of GaAs/AlGaAs-based oxide-confined VCSEL devices. Thermal-electrical part of the analysis is based on the previously reported control-volume calculation method ], ], ].…”

“…Thermal conductivities and electrical resistivities are temperature dependent, allowing for reaching selfconsistency in the model. The optical part of the simulator is based on the effective frequency method [Wenzel 1997], ] combined with the rate equations for photon and carrier densities [Osiński 2001]. The optical model allows us to calculate the lasing wavelength, modal intensity profile, emitted power and electromagnetic energy flux density inside the device.…”

A three-dimensional electrical-thermal-optical numerical solver is applied to model top-emitting oxide-confined verticalcavity surface-emitting lasers (VCSELs) with GaAs/AlGaAs multiple-quantum-well active region. CW mode of operation is simulated over a range of voltages, covering sub-threshold spontaneous emission and lasing emission. Effect of selfdistribution of electrical current is demonstrated for the first time in a self-consistent electrical-thermal-optical simulation of VCSELs.

“…The purpose of our research is to determine whether or not dielectric mirrors of alternating high/low refractive index materials, based on the design of DBR for vertical cavity surface emission lasers (VCSELs) [21], can be used in designing SPR biochemical sensors. We designed and fabricated a multilayer device to modulate the SPR signal, without changing the light source or coupling prism.…”
