Abstract
Aspects of the present disclosure are directed to wavelength division multiplexing systems comprising arrays of spectrally selective devices that are arranged on a substrate to compensate for perturbations of the spectral characteristics of the devices due to factors such as temperature non-uniformity, inherent spectral non-uniformity, and the like. As a result, shifts in the center wavelengths and/or changes in the wavelength spacing for the wavelength channels of a WDM system due to such perturbations are mitigated. In some embodiments, an array of spectrally selective devices is arranged on a substrate such that their respective wavelength channels are not linearly correlated with their physical position within the array, enabling the devices to be arranged in pairs that are subject to substantially the same environmental conditions and/or operate on nearly the same spectral range.
