Abstract: Achievable information rates are experimentally investigated in coherent fiber optical communication for different demappers by using two-dimensional and four-dimensional estimates of the channel statistics. Polarization-multiplexed 16-ary quadrature amplitude modulation with symbol rates of either 10 Gbaud… read more here.

DOI: 10.1109/jlt.2020.3046998
Abstract: Fiber nonlinearities, that lead to nonlinear signal distortion, are normally considered to be the result of an instantaneous material response with respect to the optical field. However, in addition to an instantaneous part, the nonlinear… read more here.

DOI: 10.1364/oe.26.003870
Abstract: The sensitivity of a sensor to strain or the temperature variations due to distributed Brillouin scattering are partially related to the type of fibers used and the Brillouin scattering induced effective index. In this paper,… read more here.
