| Abstract(in English) | We calculated lasing characteristics of GaInAsP microdisk injection lasers, taking account of the scattering loss at center posts and the carrier diffusion effect. We found that the optimum width of the disk edge is O.6-0.7 μm and the minimum threshold current is ～10 μA. The internal differential quantum efficiency can be 50-95 % depending on the condition of quantum-well active layer. We obtained the first room temperature CW operation with a record low threshold of 150μA, which mainly owed to the reduction of the threshold current density. The spontaneous emission factor was estimated to be 6×10^<-3>, which was much reduced by a large detuning of the lasing wavelength against the spontaneous emission peak. |
