    摘要: A photonic crystal fiber comprising: a core (20) having a refractive index; and a cladding region (10) at least substantially surrounding the core (20) and comprising a bulk material having a second refractive index that is higher that the first refractive index, the bulk material containing an arrangement of elongate, longitudinal holes that comprise hole material of a third refractive index that is lower than the first refractive index; such that an electromagnetic mode guided in the core (20) has an evanescent wave that becomes more closely confined to the vicinity of the core (20) as the wavelength of the electromagnetic mode is increased over a first range of wavelengths.

    摘要: An optical transmission system comprising a laser light source arranged to emit light having a frequency ω; and an optical transmission line adapted to guide the light, wherein said optical transmission line includes a photonic bandgap optical fibre having a core guided mode at frequency ω and an attenuation band at a frequency of ω-13 THz. The optical transmission system suppresses Raman scattered light thereby allowing high optical powers to be transmitted through optical fibre.
