Bend-resistant leaky multi-trench fiber with large mode area and single-mode operation. [PDF]
PLoS ONE, 2018 A novel structure of modified multi-trench fiber (MTF) with characteristics of bend-resistance and large mode-area is proposed. In this structure, each low refractive-index trench of traditional MTF is broken by two gaps up and down.

Large-mode-area leaky optical fiber fabricated by MCVD [PDF]
Applied Optics, 2011 A large-mode-area single-mode optical fiber based on leaky-mode filtering was prepared by a modified chemical vapor deposition (MCVD) technique. The fiber has a leaky cladding that discriminates the fundamental mode from higher-order modes. A preliminary version has a 25 μm core diameter and 0.11 numerical aperture. A Gaussian-like mode with 22 μm mode

Photonic crystal fibres: mapping Maxwell’s equations onto a Schrödinger equation eigenvalue problem [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We consider photonic crystal fibres (PCFs) made from arbitrary base materials and introduce a short-wavelength approximation which allows for a mapping of the Maxwell’s equations onto a dimensionless eigenvalue equations which has the form of the ...
