雙模光子晶體光纖及其應用

Summary

Mode photonic crystal fiber comprises a core of a substantially transparent material having a core. Said core material having a core refractive index and length, and having a core diameter. Surrounding said optical fiber further comprises a core material at the outer cladding region. The cladding region having a first substantially transparent cladding material having a first refractive index. Said first substantially transparent cladding material embedded along its length a substantially periodic array of holes having a diameter d, and is separated by a pitch Λ. Said bore having a second refractive index which is less than said first index of refraction. For the range of about 0.45-0.65 for a substantially fixed d / Λ ratio of the pitch Λ for any value of the hole diameter d and the size of the pitch Λ with to give independent of the input radiation wavelength in photonic crystal fibers within the dual-mode transmission.
