Abstract Vertical-cavity surface-emitting lasers of 1.3 μm spectral range with the active region based on the InGaAs/InGaAlAs superlattice were studied. VCSEL heterostructure was formed by a wafer-fusion of the heterostructure with an active region and two DBRs grown by molecular-beam epitaxy on InP and GaAs substrates respectively. Fabricated VCSELs have shown threshold current below 1.6 mA and frequency of small signal modulation near 9 GHz at 20°C.

A comprehensive review of temperature-related effects and thermal modeling of vertical-cavity surface-emitting lasers (VCSELs) is presented. The paper is divided into two major parts. First, the effects of temperature on device characteristics are discussed, including the temperature dependence of the longitudinal mode spectra, the threshold current, the transverse-mode structure, and the output power. A new condition is formulated for thermal matching of the Bragg mirrors and the spacer region and a comparison is made between characteristic temperatures for the threshold current (T0) and for the external quantum efficiency (Tη). In the second part, various approaches to thermal modeling of VCSELs are described. Both simplified and comprehensive thermal models are considered and both analytical and numerical approaches are discussed. A new analytical approximate method for analysis of heat-flux spreading in multilayer structures is described. The most important results obtained with the aid of these models are presented. In particular, we show that the current dependence of thermal resistance is very sensitive to VCSEL structure, and is strongly influenced by the relative distribution of heat sources and their location with respect to the heat sink.
