Abstract

Introduction

The slot type of photonic waveguide is commonly used in designing sensors based on the evanescent field because of its high evanescent field characteristics.

Methods

In this study, we introduced multiple uniform strips to improve the performance of the waveguide, aiming for a higher evanescent field ratio and reduced propagation loss to optimize the effectiveness of the sensor. The inclusion of uniform strips enhances the overall capabilities of the waveguide for evanescent field-based sensing applications.

Results

The investigation showed that the one-strip and three-strip design structures achieved maximum evanescent field values of 0.43 and 0.38, respectively, indicating significant levels. However, the three-strip design structure exhibited the minimum propagation loss, recorded at 9.1 dB/cm. Considering the variations in Evanescent Field Ratio (EFR) and propagation loss, the slot waveguide with three strips emerges as a potentially optimal design structure.

Conclusion

This conclusion is particularly relevant in the context of brain cancer applications, where heightened sensitivity is crucial. Therefore, the three-strip configuration shows promise for superior performance in detecting and addressing the complexities of brain cancer.
