Capturing Nano- and Micro-Objects in Predesignated Sites using Suspended Membranes
This invention introduces a novel method for capturing and positioning nano- and micro-scale objects at predetermined locations using suspended membranes. The technology leverages precisely engineered membrane structures to facilitate the controlled trapping of particles without requiring complex optical or mechanical manipulation techniques. This technique...

Apodized Prism Coupler for Optimized Evanescent Mode Matching Between Optical Fibers and Integrated Waveguides
This invention is a novel optical coupling apparatus and method that uses a prism-based coupler with an apodized coupling region to optimize mode matching between an optical fiber and an on-chip waveguide. This invention adapts apodization for prism coupling. It shapes the diffracted output field into a Gaussian-like profile that closely matches the...
