Approximate analytical solution for guided modes in one-dimensional arrays of identical dielectric rectangular waveguides for integrated photonics
Published 2025-08-01“…The well-known concept of an Analytical solution for a single rectangular step-index waveguide, based on separation of variables, has been modified and extended to the case of one-dimensional photonic arrays of identical waveguides. This approach proposes an analytical description of a full set of array modes, or supermodes (i.e., guided modes of a multiwaveguide system), in arrays of coupled strip-, embedded strip-, buried, strip-loaded-, rib-, inverted rib-, etc. waveguides of rectangular geometry, incorporating an arbitrary number of individual devices. …”

Hardware Implementation for Triaxial Contact-Force Estimation from Stress Tactile Sensor Arrays: An Efficient Design Approach
Published 2024-12-01“…The calculation of force vectors on the proposed hardware required an average time of 58.68 ms, with an estimation error of 12.6% for normal forces and 7.7% for tangential forces on a 10 × 10 taxel tactile sensor array. Some advantages of the developed hardware are that it does not require additional memory elements, achieves a 4× reduction in processing elements compared to a non-sparse implementation, and meets the requirements of being generalizable, scalable, and efficient, allowing an expansion of the applications of normal stress sensors in low-power tactile systems.…”
