A compact silicon waveguide mode converter, a dielectric meta-surface structure based on periodical oblique subwavelength perturbations, including a top silicon structure with oblique subwavelength perturbations etched in certain periods with period length of &#x39b;, a duty cycle and an oblique angle &#x3b8; on the SOI substrate. The invention adopts an all-dielectric meta-surface structure with oblique subwavelength perturbation, which can achieve a compact mode conversion from fundamental mode to arbitrary high-order mode of silicon waveguide, and can improve the optical communication capacity greatly.

Ultra-compact silicon waveguide mode converter based on meta-surface structure

A method and a system for automated testing of a graphic-based programming tool. The present invention includes a computer-implemented method that allows a developer to easily generate scripts for automatically testing a graphic-based programming tool using generic reusable building blocks of test code and separate decoupled parameter data. The method further allows the developer to automatically test and re-test a graphic-based programming tool using the generated scripts. The system provides a memory and a processor for implementing the automated testing methods according to embodiments of the present invention. An example application is a graphic-based programming tool used to generate screens and their underlying program logic.
