Abstract :
We achieved an emission wavelength of 2.33 μm in an InAs/InGaAs multiple-quantum-well (MQW) laser grown by metalorganic vapor phase epitaxy. MQWs with flat interfaces and good thermal stability were obtained by decreasing the growth temperature to 500°C. The PL peak wavelengths of the MQWs were controlled from 1.93 to 2.47 μm by changing the thickness of the InAs wells. For a broad-area laser, the threshold current density was 1.52 kA/cm2 and the output power was above 12 mW.
