Comparison of L–I–V and the spectral measurement results at different injection currents for VCSELs with and without AgNW film. The inset shows the dependence of the lasing wavelength on the injection current for the VCSELs with and without AgNW film on the top surface. The maximum output optical power increased from 23.4 mW to 24.4 mW, the wavelength redshift decreased from 0.085 nm/mA to 0.077 nm/mA, and the differential resistance decreased from 23.95 Ω to 21.13 Ω.
