Patent abstract
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.
