Abstract

The nonlinear characteristics of hydrogenated amorphous silicon nanowires are experimentally measured. A nonlinear coefficient, γ, with a high real part Real(γ)= 690W^-1m^-1, combined with a low imaginary part Im(γ)= 10 W^-1m^-1, resulted in a high nonlinear FOM of 5.5. Furthermore, systematic studies over hours of operational time under 2.2W of pulse peak power revealed no degradation of the optical response.
