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.
