The second-order nonlinear refractive index m (Kerr index) of cyclic olefin copolymer (TOPAS) and cyclic olefin polymers (ZEONEX, ZEONOR) is determined to be approximately 2 × 10−20 m2W−1 for all cases at the wavelength of 800 nm. The obtained values of n2 are subsequently used as input data to pulse propagation simulations based upon the generalized nonlinear Schrödinger equation.
