We have investigated the lasing characteristics of GaAs-based 1300 nm wavelength region InAs Quantum Dot Laser Diode grown by Migration Enhanced Molecular Beam Epitaxy. Under a pulsed and CW operation, we observed the state switching of lasing wavelength from ground state (1302 ㎚) to excited state (1206 ㎚) due to the gain saturation of ground state. Under a pulsed operation, Jth=92 A/㎠, λL=1311 ㎚ and under a CW operation, Jth=247 A/㎠, λL=1320 ㎚.
