Abstract: An optical fibre (20) is disclosed, the fibre is adapted in a manner such that it guides an optical signal substantially only in one non-degenerate mode, wherein an electro-magnetic field carrying the optical signal is symmetric with respect to rotation about the fibre axis. Preferably, the non-degenerate mode is the TE01 mode. In one embodiment, the optical fibre (20) includes a central hole region (22) surrounded by a concentric guiding region (24), which is in turn surrounded by a concentric cladding region 826). The guiding region (24) may comprise a Bragg reflector region. Through appropriate selection of design parameters of the fibre (20), the effective refractive index for the TM01 mode can be reduced relative to the TE01 mode to make it below a refractive index of the cladding region (269, resulting in leaking of the TM01 mode into the cladding region (26).

Abstract: 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%.

Abstract: The invention concerns a single mode dispersion-shifted optical fibre comprising: a sheathing with a given index (ns); a fibre core with a dual shape core index profile. The invention is characterised in that the fibre core index profile has an external ring with index (n3) higher than that of the sheathing (ns). The invention ensures a better control of the wavelength value for which the chromatic dispersion is nil, while preserving the other transmission characteristics of known fibres, such as mode diameter, a large effective surface and attenuation.

Abstract: A light-diffusing optical fiber having nanostructured inner and outer core regions is disclosed. The nanostructured inner core region (30) is defined by a first configuration of voids (34) that defines a first amount of light scattering. The outer core region (50) is defined by a second configuration of voids (54) that defines a second amount of light scattering that is different from the first amount of light scattering. A cladding (100) surrounds the nanostructured core. Light scattered out of the inner core region scatters from the outer core region and then out of the cladding as scattered light. Selective bending of the light-diffusing optical fiber is used to define a bending configuration that allows for tailoring the intensity distribution of the scattered light emitted from the fiber as a function of the length of the fiber.
