Optoelectronic Component with Segmented Inner Surface for Half-Space Radiation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optoelectronic components often illuminate or receive electromagnetic radiation from the entire surrounding space, leading to unwanted cross-talk and reduced efficiency, as they are unable to target emission or detection specifically to a half-space, especially in combinations of radiation-emitting and radiation-receiving components.
Innovation Solution
The design includes a carrier with a mounting surface, an optoelectronic semiconductor chip, a radiation-impermeable housing, and an optical element with specific inner surface regions that direct electromagnetic radiation into or receive it from a targeted half-space, preventing emission or detection in the opposite half-space through the use of reflective and refractive properties.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the optoelectronic component illuminates or receives electromagnetic radiation from the entire surrounding space, then the coverage area is maximized, but cross-talk increases and efficiency decreases
Solution Approach 1:
The optical element is designed with different inner surface regions having different optical properties: a first region with a first optical characteristic and a second region with a second optical characteristic. This allows different parts of the optical element to perform different functions - one region directs radiation into the target half-space while the other region prevents radiation in the opposite half-space, thereby reducing cross-talk while maintaining targeted emission coverage
Solution Approach 2:
The inner surface of the optical element is segmented into distinct regions with different optical characteristics. This segmentation allows the optical element to simultaneously achieve directional emission into a specific half-space and block emission in the opposite direction, resolving the contradiction between targeted emission and cross-talk reduction
2Manufacturing precision
If the optical element uses a single uniform inner surface design, then the manufacturing complexity is reduced, but the emission characteristic precision is insufficient
Solution Approach 1:
The optical element incorporates different inner surface regions with different optical characteristics (such as different reflectivity, refraction angles, or surface textures) to precisely control the emission characteristics in different directions, achieving high emission precision through localized optical property variations
Solution Approach 2:
A single optical element is designed to perform multiple functions: directing radiation into the target half-space, blocking radiation in the opposite half-space, and potentially focusing or scattering radiation as needed. This multi-functionality is achieved within one component, balancing manufacturing feasibility with functional precision
