Hypothesis
Can an isosceles triangular coupling structure improve optical switching and biochemical sensing capabilities?
Conclusion
The isosceles triangular coupling structure can effectively function as an optical switch and detect glucose concentrations with high sensitivity.
Supporting Evidence
- The proposed structure can achieve optical switching by changing the refractive index with applied voltage.
- The sensitivity for glucose detection reaches as high as 0.283 nm·L/g.
- The triangular coupling structure is easy to manufacture and has a simple design.
Takeaway
This study shows that a special triangle shape can help control light and measure things like sugar levels in liquids.
Methodology
Numerical and theoretical research using coupled mode theory and finite difference time domain simulations.
