  • Dynamically configurable spectral filter
    Patent number: 6275623
    Abstract: Wavelength dispersion and spatial light modulation are combined having regard for polarization management within a feedback control system for dynamically adjusting spectral power distributions among different wavelength channels. Micro-optic, hybrid, and planar implementations are proposed along with coupling schemes to larger fiber optic systems. Utility is found throughout multi-channel wavelength division multiplexing (WDM) transmission systems.

  • Optical amplifier designs for multichannel fiber optic communication networks
    Patent number: 6134047
    Abstract: A multichannel fiber optic communication network incorporates multichannel fiber optical amplifiers having different functions but designed to use substantially identical gain flattening filters. This is achieved by designing the amplifiers to have total insertion losses such that their respective internal gains (internal gain=net gain+total insertion loss) are substantially the same, most preferably within 1 dB.
