In recent years, explosively increasing data traffic has been boosting the con?tinuous demand of high speed optical interconnection inside or among data centers, high performance computers and even consumer electronics. To pursue the improved intercon?nection performance of capacity, energy efficiency and simplicity, effective approaches are demonstrated including particularly advanced digital signal processing (DSP) meth?ods. In this paper, we present a review about the enabling adaptive DSP methods for opti?cal interconnection applications, and a detailed summary of our recent and ongoing works in this field. In brief, our works focus on dealing with the specific issues for short-reach interconnection scenarios with adaptive operation, including signal-to-noise-ratio (SNR) limitation, level nonlinearity distortion, energy efficiency consideration and the de?cision precision.

For real-time massive data aggregations, we propose a WDM backbone-access network and design an integrated OADMOLT interface node to realize all-optical connections between the backbone and the access networks. Under such a network infrastructure, we formulate a Light-path-Assignment and Time-Scheduling (LATS) problem for the massive data aggregation application. We prove this problem to be NPcomplete and develop a heuristic approach based on problem decomposition. Extensive simulations demonstrate the effectiveness and the feasibility of the proposed approach.
We demonstrate a novel scheme to generate return-to-zero /carrier-suppressed return-to-zero differential phase-shift keyed (RZ/CSRZ-DPSK) signal, which needs only one Mach-Zehnder modulator (MZM). It is more cost-effe...
