Wavelength shifting of GaAs GRINSCH lasers by ion implantation

摘要

In summary, we have successfully demonstrated that proton irradiation can be used to tune the lasing wavelength of GaAs GRINSCH lasers. Up to a few nm shift can be obtained without any serious degradation in the laser performance. These results are very promising for WDM applications, as they require only small shift in wavelengths.
