TLDR
A tunable and reconfigurable functions in physical layer that can enhance network flexibility and phase sensitive amplification could be beneficial for in-line optical signal regeneration.Abstract:
This tutorial highlights challenges and opportunities in achieving efficient flexible optical networks. Optical signal processing may potentially increase network flexibility because of its functions’ transparency, tunability, and reconfigurability. We review recent advances in high-speed optical signal processing techniques that might enable flexible networks. Various optical approaches that enable key functions are discussed, including format conversion, increases in spectral efficiency, and phase-sensitive operations. We also discuss the potential utilization of basic enabling technologies, such as optical frequency combs and optical nonlinear devices.read more

Optical frequency comb generation from a monolithic microresonator
Pascal Del'Haye,Albert Schliesser,Olivier Arcizet,Tobias Wilken,Ronald Holzwarth,Tobias J. Kippenberg +5 more
TL;DR: This work reports a substantially different approach to comb generation, in which equally spaced frequency markers are produced by the interaction between a continuous-wave pump laser of a known frequency with the modes of a monolithic ultra-high-Q microresonator via the Kerr nonlinearity.
