摘要
Optical logic gates are designed using inverse-scattering theory, resulting in devices which are intrinsic and passive, having high extinction ratios and large fan out. The Boolean operation is modeled by a pair of reflection coefficients, corresponding to the `1` and `0` states of the device. When inverse scattering theory is applied, each reflection coefficient yields a unique refractive index profile. The multivalued nature of the refractive index profile is achieved by introducing nonlinearity in the core region of a thin-film waveguide, which acts as the basic structure of the devices.
