| Abstract(in English) | The methods for transverse mode control and temperature characteristics improvement in 850nm oxide confined vertical cavity surface emitting lasers (VCSELs) were investigated. First, for the transverse mode control, additional mirror loss was given to higher modes by coating dielectric film having an aperture on the top DBR. It results in narrowing spectral width and increasing the fiber-coupling efficiency. Second, simulation showed that thermal conductivity of the bottom DBR much affects on thermal property of VCSELs. Substitution of AlAs for Al_0.9Ga_0.1As in partial bottom DBR was demonstrated to reduce thermal resistance of the devices and to enable operation in high temperature of 85℃. |
