Abstract

We demonstrate an opto-electronic differential modal delay (DMD) compensation technique called spatially resolved equalization (SRE) that exploits low intermodal coupling and the resultant transverse spatial diversity in the output. Furthermore, we combine SRE with post detection electronic signal processing techniques, including decision feedback equalization, to conceptually demonstrate a simple dynamic DMD compensating receiver.
