Long Period Grating

Long period grating couples light from a guided mode into forward propagating cladding modes where it is lost due to absorption and scattering. The coupling from the guided mode to cladding modes is wavelength dependent so we can obtain a spectrally selective loss. It is an optical fiber structure with the properties periodically varying along the fiber, such that the conditions for the interaction of several co-propagating modes are satisfied.

Features

  • No reflection type
  • Low insertion loss

Applications

  • Notch band filter
  • GFF for EDFA
  • Optical fiber sensing
