Photonic Crystal-Based Polarization Converter for Optical Communication Applications
A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...
متن کاملPassive all-optical polarization switch, binary logic gates, and digital processor.
We introduce the passive all-optical polarization switch, which modulates light with light. That switch is used to construct all the binary logic gates of two or more inputs. We discuss the design concepts and the operation of the AND, OR, NAND, and NOR gates as examples. The rest of the 16 logic gates are similarly designed. Cascading of such gates is straightforward as we show and discuss. Ca...
متن کاملParallel implementation of optical symbolic substitution logic using shadow-casting and polarization.
We propose a parallel implementation method for optical symbolic substitution logic. The method uses shadow-casting principles for the efficient implementation of fundamental operations required in symbolic substitution logic; namely, image replication, spatial shifting, and combination. The use of light polarization allows for the implementation in parallel of several substitution rules withou...
متن کاملAll-optical logic circuits based on polarization properties of nondegenerate four-wave mixing
All-optical logic circuits based on the polarization properties of nondegenerate four-wave mixing are proposed. Schemes to perform multiple triple-product logic functions are discussed, and it is shown that higher-level Boolean operations that involve several bits can be implemented without resorting to the standard two-input gates. As a simple illustration of the idea, a circuit that performs ...
متن کاملA Programmable Logic-Based Implementation of Ultra-Fast Parallel Binary Image Morphological Operations
Binary morphological operations are a building block in many computer vision applications. Several iterative morphological operations are commonly performed for image analysis resulting in a significant computational load on the processing unit, especially in a real-time computer vision system. Custom designed hardware can exploit the natural parallelism exhibited in binary image morphological ...
