1. Fiber Optic Sensors for Monitoring of Lithium- and Sodium-ion Batteries
Abstract : Rechargeable batteries, particularly lithium-ion batteries, have rapidly evolved since their introduction and now dominate the market, owing primarily to their high energy and power densities. With growing demand for high-performance batteries in portable electronics and electric vehicles, the need for safe, efficient, and reliable batteries is crucial. READ MORE

2. 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

3. 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

4. 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.

5. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels
Abstract : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. READ MORE
