The wafer fusion technique is applied to a GaAs/GaAs system and the current–voltage (I–V) characteristics of the fused interface are investigated. A voltage barrier is observed at the n-GaAs/n-GaAs fused interface, but not at the p-GaAs/p-GaAs fused interface. The wafer fusion technique is also applied to laser fabrication, and a Fabry-Perot-type semiconductor laser using the GaAs/AlGaAs system is fabricated. The lasing oscillation at a wavelength of 785 nm is confirmed. The threshold current density is estimated to be as low as 2.1 kA/cm2.
