Overcoming the quantum limit of optical amplification in monolithic waveguides
Zhichao Ye, Ping Zhao, Krishna Twayana +3
Optical amplifiers are essential in numerous photonic applications. Parametric amplifiers, relying on a nonlinear material to create amplification, are uniquely promising as they c…
Over-the-fiber Digital Predistortion Using Reinforcement Learning
Jinxiang Song, Zonglong He, Christian Häger +4
We demonstrate, for the first time, experimental over-the-fiber training of transmitter neural networks (NNs) using reinforcement learning. Optical back-to-back training of a novel…
Dissipative Kerr solitons in photonic molecules
Óskar B. Helgason, Francisco R. Arteaga-Sierra, Zhichao Ye +5
Many physical systems display quantized energy states. In optics, interacting resonant cavities show a transmission spectrum with split eigenfrequencies, similar to the split energ…
Joint Superchannel Digital Signal Processing for Ultimate Bandwidth Utilization
Mikael Mazur, Jochen Schröder, Magnus Karlsson +1
Modern optical communication systems transmit multiple frequency channels, each operating very close to its theoretical limit. The total bandwidth can reach 10THz limited by the op…
An Improved Model of Nonlinear Fiber Propagation in the Presence of Kerr Nonlinearity and Stimulated Raman Scattering
Hami Rabbani, Gabriele Liga, Vinicius Oliari +4
Ultra-wideband fiber optical transmission suffers from both Kerr nonlinearity and stimulated Raman scattering (SRS). Mathematical models that address the interplay between Kerr non…
Preferred Design of Hierarchical Distribution Matching
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
Distribution matching and dematching (DM/invDM) are key functions in probabilistic shaping (PS). Recently techniques for low complexity implementation of DM/invDM have been well st…
