Notes:
Sn+ ions were implanted into silica glass at an acceleration energy of 400 keV to a dose of 2×1017 ions/cm2. Metallic Sn microcrystallites of 4–20 nm in diameter were formed to attain the average volume fraction of 28%. The dielectric function, ε, and the absolute value of the third-order optical nonlinear susceptibility, ||χ(3)||, showed dispersions around a wavelength of 500 nm, owing to surface plasmon resonance. The difference in the peak width of ||χ(3)|| and the imaginary part of ε can be explained by an effective medium theory. The maximum of ||χ(3)|| was 3×10−6 esu, which is as large as those reported for semiconductor-doped glasses.
