摘要
We report the results of measurements of the electrically induced refractive index change caused by the free-carrier effect in a silicon Schottky diode. We find that for the wavelength λ=1.3 μm, the real part of the refractive index changes by as much as ∥Δn∥∼0.01 for current densities less than 1 A/cm2. This refractive index change produced changes in the input-coupling efficiency as large as 75% in our sample geometry.
