Recently, we have demonstrated the room temperature CW operation in a GaInAsP microdisk laser with a record low threshold of 150 /spl mu/A and the smallest disk diameter of 2 /spl mu/m. We expect to further improve the performance to make this device a fundamental active element in a functional photonic circuit. However, the ultimate performance has never been discussed. In the study, we investigated the lowest threshold and the highest internal differential quantum efficiency expected in a realistic device.
