Abstract

Material growth and device fabrication of the first 1.3 μm quantum well (QW) edge emitting laser diodes in China are reported. Through the optimization of the molecular beam epitaxy (MBE) growth conditions and the tuning of the indium and nitrogen composition of the GaInNAs QWs, the emission wavelengths of the QWs can be tuned to 1.3 μm. Ridge geometry waveguide laser diodes are fabricated. The lasing wavelength is 1.3 mu;m under continuous current injection at room temperature with threshold current of 1 kA/cm2 for the laser diode structures with the cleaved facet mirrors. The output light power over 30 mW is obtained.
