Optical systems and devices using long period spectral shaping devices

In accordance with the present invention, optical fiber communications systems are provided with one or more long period spectral shaping devices to shift light of unwanted wavelength from guided modes into non-guided modes. Such devices can be used for removing unused laser pump energy, for removin...
