Enhancing Nonlinear Properties of Gallium Nitride via Doping for Advanced Modulation

The nonlinear characteristics of gallium nitride (GaN) present exciting opportunities for achieving modulation through various techniques. Research has shown that the introduction of iron and magnesium doping can effectively alter the nonlinear absorption properties of GaN crystals. Similarly, studies have reported successful modifications to the defect aperture properties of GaN nanowires. Further investigation into enhancing the nonlinear properties of GaN through strategic doping structures holds significant promise. This research direction is crucial for unlocking the full potential of GaN in advanced modulation applications.
