摘要： The present invention provides a method of designing a waveguide having a refractive index profile associated with substantially diffraction-free propagation of light. The method includes the steps of creating a mathematical model describing an optical field associated with the diffraction-free propagation and deriving parameters for the design of the waveguide from the mode. The invention also provides a waveguide (20) that has a central region (12) of lower refractive index surrounded by a region of higher refractive index, the waveguide being arranged such that, in use, the intensity distribution of guided light has a maximum in the central low-index region (12). The waveguide may include a plurality of light confining elements (16) {for example, air channels} arranged such as to create a profile of effective refractive index similar to that of a Fresnel lens.

摘要： Micro-structured optical fibres are improved with respect to increasing the dispersion, both to large negative or large positive values, in a first fibre design in which the fibre has a micro-structured core region being surrounded by a micro-structured cladding region with cladding features being large compared to a predetermined wavelength of light, which can be guided through the fibre. Preferably, the effective index of refraction of the core region, Nco, is larger than the effective index of refraction of the cladding region Ncl, at the predetermined wavelength of light. It is further preferred that the refractive index of one or more of the core features is lower than the refractive index of the core material. Increased dispersion is also obtained by a second optical fibre design in which the fibre has two cladding regions, where the inner cladding region may be micro-structured with inner cladding features and having an effective refrafctive index that is larger than the effective refractive index of the outer cladding region at the operating wavelengths, i.e. the fibre has an inner cladding with a raised effective refractive index. For the second fibre design it is preferred that the outer cladding region is micro-structured with outer cladding features. There is further provided a third optical fibre design, which may be used for non-linear applications, and in which the use of a raised, inner cladding provides the flexibility to obtain fibres with very, small cores and near-zero dispersion over a broad wavelengths range at near-infrared wavelengths. In the third fibre design, the optical fibre has a core region surrounded by an inner cladding region with a number of inner cladding features disposed in an inner cladding material, while the inner cladding region is surrounded by an outer cladding region. In the third design the inner cladding features have a refractive index that differs from the refractive index of the inner cladding material, and the inner cladding region has an effective refractive index Ni that is larger than_the effective refractive index No of the outer cladding region at the operating wavelength. The core region of the third design may be a substantially solid core with an effective refractive index Nco being larger than Ni at the operating wavelength. For the third design, the outer cladding region may also comprise a number of outer cladding features disposed in an outer cladding material, with the outer cladding features having a refractive index that differs from the refractive index of the outer cladding material. For the third fibre design it is preferred that the effective refractive index difference between the core region and the inner cladding region is greater than about 5%.

摘要： Shunt fibers having a photonic bandgap cladding region including one or more hollow guiding regions of which one guiding region is configured as the core and one or more other guiding regions are configured as shunts, respectively, provide nearly single mode transmission in the core. The effective mode index of unwanted core modes and modes in one or more shunts are matched closely enough such that higher order modes will selectively couple to the shunt modes by resonant phase matching in the presence of fiber variations. The shunts are designed to have relatively higher losses thereby effectively dissipating power in the higher order modes at a faster rate.

摘要： A photonic-crystal fibre comprises a core (20) and a cladding (10) with longitudinal holes. The refractive index of the core is lower than that of the cladding bulk material, e.g. by fluorine doping of the core material. The holes are air-filled cavities extending along the longitudinal direction of the fibre. One property of the fibre is that a guided mode having longer wavelength is more confined in the core than a mode with a shorter wavelength. Such a fibre may have a cut-off wavelength lambda c such that the fibre is unable to guide in its core light of wavelengths shorter than lambda c.

摘要： A fiber, such as a photonic bandgap fiber, is provided, the fiber including a core and a cladding. The core can extend longitudinally and can have a gain medium configured to provide laser amplification to signal radiation propagating along the core. For example, the gain medium may include a dopant configured to provide laser amplification, when activated by excitation radiation, to signal radiation propagating along said core. The cladding can be radially exterior to the core, and can be configured to resonantly reflect at least some excitation radiation propagating transversely to the core and to generally transmit signal radiation propagating transversely to the core. The core may have an effective core index of refraction that is lower than an effective cladding index of refraction. Associated methods and apparatuses are also provided.

An object of the invention is achieved by a micro- structured optical fiber, which is adapted to guide light by the photonic bandgap effect and to have one or more pass bands and at least one stop- band over a wavelength range from λ stop1 to λ stop2- In an aspect of the invention, the at least one stop-band provides filter functions that suppress nonlinear effects. In another aspect, the core region is actively doped, and the active material has an emission spectrum with a higher value of the emission cross section σ E at a wavelength λ ASE between λ stop1 and λ stop2 than outside said wavelength range such that amplified spontaneous emission and lasing within the wavelength range from λ stop1 to λ stop2 is reduced. In still another aspect, the optical fiber exhibits photonic bandgaps at different wavelength ranges in different radial directions of a cross section of the optical fiber.

摘要： Micro-structured optical fibres are improved with respect to increasing the dispersion, both to large negative or large positive values, in a first fibre design in which the fibre has a micro-structured core region being surrounded by a micro-structured cladding region with cladding features being large compared to a predetermined wavelength of light, which can be guided through the fibre. Preferably, the effective index of refraction of the core region, Nco, is larger than the effective index of refraction of the cladding region Ncl, at the predetermined wavelength of light. It is further preferred that the refractive index of one or more of the core features is lower than the refractive index of the core material. Increased dispersion is also obtained by a second optical fibre design in which the fibre has two cladding regions, where the inner cladding region may be micro-structured with inner cladding features and having an effective refractive index that is larger than the effective refractive index of the outer cladding region at the operating wavelengths, i.e. the fibre has an inner cladding with a raised effective refractive index. For the second fibre design it is preferred that the outer cladding region is micro-structured with outer cladding features.
