Abstract
Spatial division multiplexing (SDM) systems are essential to overcome the increasing demand for higher bandwidth data services. Nevertheless, SDM employment is challenging and complex impairments need to be addressed (e.g., crosstalk and nonlinearities). The use of spatial light modulator (SLM) in core/mode division multiplexing is foreseen to improve channel compensation, by using it as a diffractive device to reconstruct images from computer generated holograms (CGHs). The transparency and passive nature of the application of optical transforms (e.g., Haar transforms (HT) fully in the optical domain) for compression/decompression of data, may allow energy saving and processing capacity relief, by reducing redundant or negligible data. In this study, the concept of combining HT and CGH to improve the processing/storing of high bandwidth demanding data associated with SDM systems is presented. Exploring the implementation of parallel processing of 2D data through integrated optics, for all-optical wavelet transforms and compression, and the use of CGH for spatial light modulation.
