Reconfigurable Self-Phase Modulation Enabled by Cascaded Nonlinear Backaction in Integrated Photonics

Author(s): Chaohan Cui, Liang Zhang, and Linran Fan Self-phase modulation is ubiquitous in optical systems: It provides foundational functionality to numerous photonic technologies, such as soliton generation and ultrafast pulse compression. However, it remains challenging to directly modify the coefficient of self-phase modulation, which is typicall… [Phys. Rev. Lett. 134, 103803] Published Fri Mar 14, 2025
