    • Disclosed is a dispersion managed optical waveguide fiber. The power loss due to four wave mixing is kept low by making the waveguide from sub-lengths of fiber which have non-zero dispersion. The sign of the total dispersion of the sub-lengths is made to alternate along the length of the waveguide, thereby allowing the total dispersion of the waveguide to be managed to a pre-selected target value. It has been discovered that the best performance is obtained when the zero dispersion wavelengths of the sub-lengths are widely and asymmetrically separated. Advantages are realized when the core refractive index profil is changed for sub-lengths having total dispersion of different sign.
    • 公开了一种色散管理光波导光纤。 通过使波导从具有非零色散的光纤的子长度来保持由于四波混频引起的功率损耗。 使子长度的总色散的符号沿着波导的长度交替,从而允许将波导的总色散管理到预选的目标值。 已经发现,当子长度的零色散波长被广泛和不对称地分离时,获得最佳性能。 当对具有不同符号的总色散的子长度改变纤芯折射率轮廓时,实现优点。
