SUMMARY

The discussion focuses on detecting TE (Transverse Electric) mode and TM (Transverse Magnetic) mode in optical waveguides. It is established that the key differentiator between these modes is their polarization characteristics. Specifically, TE mode features electric field vectors that are perpendicular to the direction of propagation, while TM mode has electric field vectors parallel to the direction of propagation. Understanding these polarization differences is essential for effective mode detection in optical systems.

PREREQUISITES
  • Basic understanding of optical waveguides

If there are TE mode and TM mode in an optical waveguide, how to detect them?

Thank you!
