What are the advantages of using a waveguide?

Some of the advantages of using waveguides are:

  • They can handle very large power in kilowatts
  • They have low insertion loss and low attenuation
    They provide wide bandwidth and high frequency transmission
  • They can direct power precisely to where it is needed
  • They can function as a high-pass filter due to their cut-off frequency
  • They can modulate, amplify, or switch light signals for various optoelectronic applications.
