Thermal conductivity reduction effect of thin layer on thermal resistance of vertical cavity surface emitting lasers
2018
Japanese Journal of Applied Physics
An accurate design of the thermal resistance of vertical cavity surface emitting lasers (VCSELs) is important for high efficiency and high output power density of a VCSEL array. Although there are reports on the thermal conductivity of a thin layer that changes from that of bulk material due to phonon scattering, its influence on VCSELs has not been clarified. In this study, we analyzed the thermal resistance of VCSELs by numerical simulation considering the thermal conductivity reduction
