We study the localization properties of the eigenstates in the KronigPenney model with weak compositional and structural disorder. The main result is an expression for the localization length that is valid for any kind of selfand inter-correlations of the two types of disorder. We show that the interplay between compositional and structural disorder can result in anomalous localization. Pacs nu...

Real-time 10,000 km transmission over a straight-line link is achieved using software-defined multi-modulation format receiver implemented on commercial off-the-shelf general-purpose graphics processing unit (GPU). Minimum phase 1 GBaud (QAM) signals are transmitted and successfully received after detection with Kramers-Kronig (KK) coherent receiver. 8-, 16-, 32-, 64-QAM 7600, 5600, 3600, 1600 ...
