Thin film optical computing

摘要

An optical integration technique using thin film technology is based on a nonlinear interface with a diffusive or saturated Kerr-like nonlinearity. Solid state multiplexing is implemented with thin film multilayer stacks resulting in polarizers and phase retarders matched to the interface. The simplicity of the integration architecture is demonstrated by designing a thin film half-adder, a full adder and a carry-propagate adder.
