Photonic crystal (PhC) heterostructures combining segments of slightly different PhCs have been used to develop photonic devices, such as high-performance add/drop filters and microcavities with ultrahigh-quality factors. In this paper, we present a highly efficient computational method for simulating PhC heterostructure devices based on a two-dimensional (2-D) model. The method delivers high-accuracy...
Photonic crystal heterostructure mode-gap cavities, constructed by connecting two kinds of photonic crystal waveguides with different lattice constants, are important photonic devices. In this paper, we extend the Dirichlet-to-Neumann map method to analyze mode-gap cavities in two-dimensional photonic crystal heterostructures. The efficiency of our method is illustrated by numerical simulations.
The concept of Triclusters has been investigated recently in the context of two relational datasets that share labels along one of the dimensions. By simultaneously processing two datasets to unveil triclusters, new useful knowledge and insights can be obtained. However, some recently reported methods are either closely linked to specific problems or constrain datasets to have some specific distributions...
