- 14. Mode TE transverse electric (TE) mode: A mode whose electric field vector is normal to the direction of propagation . Note: TE modes may be useful modes in waveguides. In an optical fiber , TE and TM modes correspond to meridional rays . meridional ray: In fiber optics , a ray that passes through the optical axis of an optical fiber (in contrast with a skew ray , which does not). 02/02/11 © 2010 Universitas Negeri Jakarta | www.unj.ac.id |
- 16. Cutt0ff wavelength cutoff wavelength: 1. The wavelength corresponding to the cutoff frequency . ( 188 ) 2. In an uncabled single-mode optical fiber , the wavelength greater than which a particular waveguide mode ceases to be a bound mode . ( 188 ) Note 1: The cutoff wavelength is usually taken to be the wavelength at which the normalized frequency is equal to 2.405. Note 2 : The cabled cutoff wavelength is usually considered to be a more functional parameter because it takes into consideration the effects of cabling the fiber. 02/02/11 © 2010 Universitas Negeri Jakarta | www.unj.ac.id |
- 18. Mode TM transverse magnetic (TM) mode: A mode whose magnetic field vector is normal to the direction of propagation . Note: TM modes may be useful in waveguides. In an optical fiber , TE and TM modes correspond to meridional rays . 02/02/11 © 2010 Universitas Negeri Jakarta | www.unj.ac.id |
- 19. Mode TEM transverse electric and magnetic (TEM) mode: A mode whose electric and magnetic field vectors are both normal to the direction of propagation . Note: The TEM mode is the most useful mode in a coaxial cable or Radio propagation. 02/02/11 © 2010 Universitas Negeri Jakarta | www.unj.ac.id |
