摘要： Holey fibers provide optical propagation. In various embodiments, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and higher modes of a signal, thereby allowing the non-fundamental modes to be substantially eliminated by leakage over a given length of fiber. Fine tuning of leakage losses can be performed by adjusting the hole dimension and/or spacing to yield a desired operation with a desired leakage loss of the fundamental mode. Resulting holey fibers have a large hole dimension and spacing, and thus a large core, when compared to traditional fibers and conventional fibers that propagate a single mode. Other loss mechanisms, such as bend loss and modal spacing can be utilized for selected modes of operation of holey fibers.

One fabrication method includes: sealing silica PCF and a quantity of magnesium within a container, the quantity of magnesium defined by 2Mg(g)+SiO2(s)->2MgO(s)+Si(s); converting silica PCF to a reacted PCF through magnesiothermic reduction; and converting the reacted PCF to the fabricated silicon PCF by selective dissolution of the reacted PCF in an acid.

摘要： The fibre comprises a core (2) having an index N and diameter of 10 μm or more, surrounded by a ring (4) having an index N+Δn and thickness ΔR, and cladding (6) surrounding the ring and comprising for example air gaps (8). According to the invention: Δn≧10−3 and ΔR=α/(Δn)β [1] where: 5×10−4 μm≦α≦5×10−2 μm and 0.5≦β≦1.5. The numbers α and β are dependent on the wavelength λ of the light guided by the fibre, the number of missing gaps therein, the diameter d of the gaps, the spacing Λ thereof and N. To design the fibre, λ, the number of missing gaps, d/Λ, the core doping content, Λ0 and Δn are chosen; and ΔR is determined using equation [1] so as to obtain a flattened fundamental mode.
