Area of Science:
- Optics and Photonics
- Materials Science
Background:
- Strip-loaded waveguides are crucial components in integrated optics.
- Understanding mode propagation and field distribution is essential for device design.
Purpose of the Study:
- To analyze mode propagation and field distribution in strip-loaded waveguides.
- To investigate the effect of a high refractive index loading film.
Main Methods:
- Theoretical analysis of waveguide modes.
- Examination of field distribution patterns.
Main Results:
- Propagation constant is significantly altered by loading film thickness near cutoff.
