Reflective Structures for Waveguide Light Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting resonator structures face challenges in efficiently coupling electromagnetic radiation into a waveguide due to difficulties in positioning the waveguide conduit relative to the nano-resonating structures, particularly when the angle of emitted light makes it hard to capture all emitted radiation effectively.
Innovation Solution
The use of reflective structures on the substrate to redirect and focus the emitted electromagnetic radiation into a waveguide conduit, which can be integrated with the nano-resonating structure, ensuring optimal capture of the emitted light, and potentially using a single waveguide conduit for multiple nano-resonant structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a waveguide conduit is positioned close to nano-resonating structures to capture emitted electromagnetic radiation, then the capture efficiency of the waveguide conduit is improved, but the positioning difficulty increases due to the specific angle of emitted light
Solution Approach 1:
A reflective structure is introduced as an intermediary element between the nano-resonating structure and the waveguide conduit. This reflective structure redirects the emitted electromagnetic radiation at the required angle into the waveguide conduit, eliminating the need for precise direct positioning. The reflective structure mediates the interaction by changing the propagation direction of the radiation, thus solving the positioning difficulty while maintaining high capture efficiency.
2Loss of energy
If multiple nano-resonant structures are served by separate waveguide conduits to ensure optimal light capture, then the capture efficiency is improved, but the device complexity increases
Solution Approach 1:
A single waveguide conduit is designed to serve multiple nano-resonant structures by incorporating a reflective structure that collects and redirects light from multiple sources into one conduit. This multi-functional design allows one waveguide conduit to perform the function that would otherwise require multiple separate conduits, thereby reducing device complexity while maintaining optimal light capture efficiency from each nano-resonant structure.
