To combine the technical functions and advantages of solid-core fiber Bragg gratings (FBGs) and hollow-core optical fibers (HCFs), the hollow and filled FBGs in nano-bore optical fibers (NBFs) with nano-bore in the GeO2-doped core are proposed. The fundamental mode field, effective mode index, and confinement loss of NBF with 50 nm– 7 μ m -diameter hollow and filled nano-bore are numerically investigated by the finite element method. The reflected spectra of FBGs in NBFs are obtained by the transmission matrix method. The hollow FBGs in NBFs can be acheived with (∼5% power fraction in the bore and the (∼0.9 reflectivity when bore diameter is less than 3 μ m . The filled FBGs can be realized with (∼1% power fraction and 0.98 reflectivity with different fillings including o-xylene, trichloroethylene, and chloroform for 800-nm bore diameter. The feasibility of the index sensing by our proposed NBF FBG is also analyzed and discussed. The experimental fabrication of hollow and filled FBGs are discussed and can be achieved by current techniques. The aim of this work is to establish a principle prototype for investigating the HCFs and solid-core FBGs-based fiber-optic platforms, which are useful for applications such as the simultaneous chemical and physical sensing at the same position.

“…Finally, considering an effective cross section area of ~0.7 μm 2 and a nonlinear refractive index n 2 ~5 ⋅ 10 −19 m 2 /W [50], the waveguide nonlinear parameter, as defined in [47], can be estimated as γ ~3000 W −1 km −1 . A more sophisticated approach would include the influence of the longitudinal component of the guided modes to compute γ [51,52]. However, for the contrast index, waveguide dimensions, and spectral range considered in the simulations of the next section, the correction introduced by such approach should be relatively small as can be estimated from Fig.…”

Ultra-broadband two-pump optical parametric amplifier in tellurite waveguides with engineered dispersion

et al. 2017

The capacity of communication networks may be significantly improved by simply enhancing the optical amplifier bandwidth. This paper presents a numerical investigation of an ultra-broadband, low-ripple, two-pump-optical parametric amplifier (2P-OPA) that employs a tellurite glass buried-channel type nano-waveguide as nonlinear medium. The nano-waveguide was designed as a 25-cm-long Archimedean spiral that occupies a footprint of only ~2.5 mm², with a ~0.7 μm² effective cross section. Its zero-dispersion wavelength is ~1550 nm, the nonlinear coefficient is ~3000 W^-1 km^-1 _, and the attenuation coefficient is ~0.5 dB/m (1100 to 1900 nm). Simulations suggest a 2P-OPA based on such waveguide will be able to amplify 243 QPSK input channels modulated at 56 Gbps over 102 nm bandwidth, over metropolitan area network scales.
