WebA long-period fiber 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 ... WebThe long-period grating (LPG) has a period typically in the range 100 µmto1mm, as illustrated in ﬁgure 1. The LPG promotes coupling between the propagating core mode and co-propagating cladding modes. The high attenuation of the cladding modes results in the transmission spectrum of the ﬁbre containing a series of attenuation bands centred
