采用Z扫描实验技术测量了1060 nm下InP的双光子吸收系数β、束缚电子非线性折射率γ和自由载流子折射率σr。我们发现β <$90 cm/GW,γ <$− 1.5×10− 12 cm 2/W和σr <$− 0.4×10− 21 cm 3,并将这些值与理论计算进行比较。
The Z-scan experimental technique has been employed to measure the two-photon absorption coefficient, β, bound electronic nonlinear refractive index, γ, and free-carrier refractive index, σr, in bulk, undoped InP at 1060 nm. We find β≈90 cm/GW, γ≈ − 1.5×10−12cm2/W and σr≈ − 0.4×10−21cm3, and compare these values to theoretical calculations.
