Optical pulse transmission lines

摘要

An optical pulse transmission line portion 10, having dispersion slope compensation, comprising an optical waveguide 12 (length L1, dispersion parameter D1) having a dispersion slope parameter (S1) of a first sign, and dispersion compensation means 14 (length L2, dispersion parameter D2) having a dispersion slope parameter (S2) of the opposite sign. The path average dispersion () of the transmission line portion being: 1 $⟨D⟩=\frac{D_{1}it{S}_2-D_{2}it{S}_1}{S_2-S_1}$ Optical pulse transmission line portion components and an optical pulse transmission line having dispersion slope compensation are also provided. A further aspect of the invention provides an optical pulse transmission line element, having dispersion compensation and dispersion slope compensation, comprising an optical waveguide (length L1, dispersion parameter D1, dispersion slope parameter S1) and first and second dispersion compensation means (lengths L2, L3, dispersion parameters D2, D3, dispersion slope parameters S2, S3). The path average dispersion () of the transmission line element (total length L) being: 2 $⟨D⟩=\frac{D_{2}it{S}_3-D_{3}it{S}_2}{S_3-S_2}it(1-\frac{L_1}{\mathrm{L<}}$
