Formation and Collision of Multistability-Enabled Composite Dissipative Kerr Solitons

Tobias Kippenberg, Wenle Weng

Multistability in Kerr resonators which are driven by continuous or modulated optical waves gives rise to the superposition of distinct nonlinear states, yielding a unique platform for studying complex soliton dynamics. Here, by pumping a crystalline micro ...

State-Of-The-Art of Research on Distributed Optical Fibre Sensors

Luc Thévenaz, Zhisheng Yang

Optical fibres offer the possibility to realize distributed sensing, which means that each point along the fibre can separately and selectively sense quantities such as temperature, strain, acoustics, and pressure, in total similarity to a real organic ner ...

Optical Sinc-Shaped Nyquist Pulse Source Based on a Single Mach-Zehnder Modulator

Camille Sophie Brès, Jianqi Hu, Simon Julien Fabbri

We present a precise and flexible Sinc-shaped Nyquist pulse source based on a single Mach-Zehnder modulator. The use of multi-harmonic RF signals provides direct control on the Nyquist pulse train generation. The variable comb source is demonstrated by sel ...

All-optical flip-flop based on dynamic Brillouin gratings

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov

One of the most essential building blocks in modem electronics is the flip-flop. A flip-flop operates bi-stably between two states, remaining at a given output level (high or low level) until a specific input control signal changes. For many years, photoni ...
