Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved
features beyond what conventional optical fibers can offer. Due to their unique geometric …

An optical trap forms a restoring optical force field to immobilize and manipulate tiny objects.
A fiber optical trap is capable of establishing the restoring optical force field using one or a …

Optical fibre sensors make use of diverse physical effects to measure parameters such as
strain, temperature and electric field. Here we introduce a new class of reconfigurable fibre …

Precise manipulation and sorting of nanomaterials cannot rely on techniques used for micro-
and macro-scale objects because of their nanoscale size, which is smaller than the …

Since 1908, when Mie reported analytical expressions for the fields scattered by a spherical
particle upon incidence of plane-waves, generalizing his analysis for the case of an arbitrary …

We report a novel optothermal trapping mechanism that occurs in air-filled hollow-core
photonic crystal fiber. In the confined environment of the core, the motion of a laser-guided …

We demonstrate the first soft-glass hollow core photonic crystal fiber. The fiber is made from
a high-index lead-silicate glass (Schott SF6, refractive index 1.82 at 500 nm). Fabricated by …

We show how microparticles can be moved over long distances and precisely positioned in
a low-loss air-filled hollow-core photonic crystal fiber using a coherent superposition of two …

Micrometer-sized particles are trapped in front of an air-filled hollow-core photonic crystal
fiber using a novel dual-beam trap. A backward guided mode produces a divergent beam …

We report the use of a liquid‐filled hollow‐core photonic crystal fiber (PCF) as a highly
controlled photochemical reactor. Hollow‐core PCFs have several major advantages over …
