- 11Conversion between the cgs units presented here and MKS units can be accomplished according to the following: χ(3) [m2 V−2, MKS] = (4π/9 × 10−8)χ(3) [esu or cm2 statVolt−2, cgs]. Accordingly, the values of |χ(3)| in Table 2 exhibit an average value of 5.8 × 10−19 m2 V−2. These third-order susceptibilities can also be converted to non-linear refractive indices (n2) according to the following equation: n2 = 3Reχ(3)/(4ϵ0cn02), where n0 is the refractive index of the medium. Consequently, the values of Reχ(3) in Table S2 can be converted to an average value of n2 = −5.0 × 10−17 m2 W−1.
- 14The values of Imχ(3) in Table S2 can be converted to two-photon absorption coefficients (β) according to the following equation: β = 3π(Imχ(3))/(ϵ0cn02λ), where n0 is the refractive index of the medium and λ is the excitation wavelength.
- 18Guest-host blends with slightly lower doping wt% (25 wt% instead of 50 wt%) were chosen for the organic claddings due to larger linear losses found in the SOH waveguides than those measured in free-space (see Table 2). As no additional measures were taken to ensure optimal interfacial coupling between the cladding and guide, this discrepancy is likely due to additional scattering losses in the SOH geometry. Nonetheless, the optical losses of the 25 wt% AJBC 1723 and 1725 cladding films were found to be 17 and 10 dB/cm, respectively.
