Dispersion and polarization properties in photonic crystal fibers

Fibre Bragg grating photowriting in microstructured optical fibres for refractive index measurement

“…Since the beginning of the 1990s, photonic crystal fibres have been an increasing topic of interest in R&D laboratories because of their large potentialities in several application fields, such as nonlinear effects [1,2], dispersion compensation [3,4], high power propagation [5] and sensors [6]. Classically, we can distinguish photonic crystal fibres guiding light by the photonic bandgap effect [7] and microstructured optical fibres (MOFs) guiding light by total internal reflection.…”

Tilted Fiber Bragg Grating photowritten in microstructured optical fiber for improved refractive index measurement

“…Because the refractive index of the core is higher than the highest effective index of the modes of the cladding, these fibers simply guide light by total internal reflection. Since a few years, such fibers are a great matter of concern for the optical fiber community due to their potential in several application fields (non-linear effects [1,2], dispersion management [3,4], high optical power transmission [5], and sensing [6]).…”
