Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If doping is increased in waveguide layers to improve electrical conductivity, then electrical conductivity is improved, but electromagnetic radiation absorption increases
Solution Approach 1:
The patent applies local quality by implementing different doping levels in different spatial regions of the waveguide layer. Specifically, peak doping regions are created at interfaces between layers with different band gaps where high doping concentration is needed for electrical conductivity, while the central region of the waveguide layer maintains low doping concentration to minimize electromagnetic radiation absorption. This spatial variation in doping quality resolves the contradiction between conductivity and absorption.
Solution Approach 2:
The waveguide layer is segmented into distinct doping regions: peak doping regions at the interfaces and a low-doped central region. This segmentation allows each region to fulfill its specific function - the peak regions provide electrical conductivity at critical interfaces, while the central region minimizes optical absorption, thereby resolving the technical contradiction.

If peak doping regions are introduced at interfaces to reduce voltage drop, then voltage drop is reduced, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the doping concentration parameter at specific locations (interfaces between layers with different band gaps). The doping concentration is changed from low to high at these critical interfaces, creating peak doping regions that reduce voltage drop. This controlled parameter change achieves the desired electrical performance while managing device complexity.
