We investigate the impact of disorder on the propagation of photonic crystal waveguide
modes using phase-sensitive optical low-coherence reflectometry. Combined with a suitable …

Chromatic dispersion is an important fiber attribute affecting transmission performance over
optical fibers. Various chromatic dispersion measurement methods have been developed …

We propose an improvement of the interferometric method used up to now to measure the

Acousto-optic interaction in optical fibers is exploited for the accurate and broadband
characterization of two-mode optical fibers. Coupling between LP_01 and LP_1m modes is …

Dispersive fiber is well-regarded as the most viable candidate for realizing efficient optical
time-stretch process–an ultrafast spectroscopic measurement technique based on the …

Few-mode optical fibers (FMFs) are useful for many applications such as space-division-
multiplexing (SDM), high laser power generation and transport, dispersion compensation …

Emergence of new fibers families induces considerable requirements in terms of
characterization and metrology (group delay, chromatic dispersion, birefringence, bending …

We propose and experimentally demonstrate a simple and accurate technique for
measuring differential mode group delay (DMGD) in few mode fibers (FMF). A frequency …
