Highly Birefringent Two-Mode Photonic Crystal Fibers With Near-Zero Flattened Dispersion
IEEE Photonics Journal, 2011 Through introducing three sizes of holes in cladding, highly birefringent two-mode photonic crystal fibers (PCFs) are proposed. The full-vector finite-element method (FEM) is applied in the calculation of the transverse electric field vector ...

Third-order chromatic dispersion stabilizes Kerr frequency combs
, 2014 Using numerical simulations of an extended Lugiato-Lefever equation, we analyze the stability and nonlinear dynamics of Kerr frequency combs generated in microresonators and fiber resonators taking into account third-order dispersion effects.

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
