1. All-optical nonlinearity mitigation in fiber-optic communications
Abstract : The two main factors limiting the data throughput in modern fiber-optic communication links are the noise added by amplifiers and the nonlinear response of the optical fiber due to the Kerr effect. Today there are communication systems operating remarkably close to the limits set by these two factors. READ MORE

2. Channel-Aware Multilevel Coded Modulation for Coherent Fiber-Optic Communications
Abstract : The past decades have shown an ever-increasing demand for high-rate Internet services, motivating a great effort to increase the spectral efficiency of optical networks. In general, fiber-optic links are non-Gaussian, and in contrast to additive white Gaussian noise (AWGN) channels, there is no standard framework for quantifying fundamental limits or designing capacity-approaching coding schemes for such channels.

3. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications
Abstract : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. READ MORE

4. Voronoi Constellations for Coherent Fiber-Optic Communication Systems
Abstract : The increasing demand for higher data rates is driving the adoption of high-spectral-efficiency (SE) transmission in communication systems. The well-known 1. READ MORE

5. Fiber-optic communications with microresonator frequency combs
Abstract : Modern data communication links target ever-higher information throughput. To utilize the available bandwidth in a single strand of fiber, optical communication links often require a large number of lasers, each operating at a different wavelength. READ MORE
