Graphene-clad tapered fibre: effective nonlinearity and propagation losses

چکیده
We derive pulse propagation equation for a graphene-clad optical fibre, treating optical response of graphene and nonlinearity of the dielectric fibre core as perturbations in asymptotic expansion of Maxwell equations. We analyse the effective nonlinear and attenuation coefficients due to the graphene layer. Based on the recent experimental measurements of the nonlinear graphene conductivity, we predict considerable enhancement of the effective nonlinearity for sub-wavelength fibre core diameters.

متن کاملGraphene-clad microfibre saturable absorber for ultrafast fibre lasers
Graphene, whose absorbance is approximately independent of wavelength, allows broadband light-matter interactions with ultrafast responses. The interband optical absorption of graphene can be saturated readily under strong excitation, thereby enabling scientists to exploit the photonic properties of graphene to realize ultrafast lasers. The evanescent field interaction scheme of the propagating...
متن کاملOn the Dispersion Relations of Tapered Core Optical Fibers with Liquid Crystal Clad
The paper deals with the case of a three-layer liquid crystal tapered optical fiber (LCTOF) for which the dispersion relations are deduced corresponding to the TE and the TM modes. For the LCTOF under consideration, the outermost clad section is made of liquid crystal material with radial anisotropy whereas the core and the inner clad are homogeneous, non-magnetic and isotropic dielectric regio...
متن کاملDouble-clad fiber with a tapered end for confocal endomicroscopy
We present a double-clad fiber coupler (DCFC) for use in confocal endomicroscopy to reduce speckle contrast, increase signal collection while preserving optical sectioning. The DCFC is made by incorporating a double-clad tapered fiber (DCTF) to a fused-tapered DCFC for achromatic transmission (from 1265 nm to 1325 nm) of > 95% illumination light trough the single mode (SM) core and collection o...
متن کاملLoss in Microstructured Fibre with a Short Taper
Losses in tapered microstructured fibres have been calculated as a function of shape and length using finite-difference time-domain calculations. Minimal losses are incurred even in non-optimally shaped tapers shorter than 100 micron. The results have important implications for splice losses and device applications.
