摘要：

We have created and studied the properties of semiconductor lasers on InAs/GaAs quantum dots with a maximum modal gain of 46 cm(-1) at a wavelength of 1325 nm achieved due to increased optical confinement factor and optimized heterostructure growth parameters. In a wavelength interval of 1315-1345 nm, the modal gain exceeded 20 cm(-1) at a current density of 500 A/cm(2).
