Photonic crystal (PC) is an emerging optical microstructure material with adjustable
dielectric constant, which can vary with its space periodically. It has exhibited excellent …

Clinical diagnostic devices provide new sources of information that give insight about the
state of health which can then be used to manage patient care. These tools can be as simple …

Conventional solid-core optical fibres require highly transparent materials. Such materials
have been difficult to identify owing to the fundamental limitations associated with the …

Since the early conceptual and practical demonstrations in the late 1990s, Hollow-Core
Photonic Band Gap Fibres (HC-PBGFs) have attracted huge interest by virtue of their …

Photonic crystal fibers (PCFs) offer new possibilities of realizing highly birefringent fibers
due to a higher intrinsic index contrast compared to conventional fibers. In this letter, we …

Broader bandwidths, denser channel spacing, and higher signal intensities all makes
nonlinear effects more critical to the performance of telecommunications systems. This …

Recent progress on numerical modeling methods for photonic crystal fibers (PCFs) such as
the effective index approach, basis-function expansion approach, and numerical approach …

We describe a multipole formulation that can be used for high-accuracy calculations of the
full complex propagation constant of a microstructured optical fiber with a finite number of …

The wavelength dependence and the structural dependence of leakage loss and group
velocity dispersion (GVD) in air-core photonic bandgap fibers (PBGFs) are numerically …

Silica-based optical fibers have been one of the engineering triumphs of the last few
decades. Yet after an initial period of intense development that revolutionized …
