Engineering Rogue Waves via Multimode Interactions in Integrated Waveguides
Gülsüm Yaren Durdu, Azka Maula Iskandar Muda, Uğur Teğin
We explore rogue wave formation in multimode silicon nitride (SiN) waveguides with multimode nonlinear Schrödinger equation-based simulations. Pure fundamental-mode excitat…
Spatiotemporal Nonlinear Pulse Dynamics in Multimode Silicon Nitride Waveguides
Azka Maula Iskandar Muda, Uğur Teğin
We present an open-source multimode nonlinear Schrödinger equation-based simulation to investigate spatiotemporal nonlinear pulse propagation in thin-film silicon nitride (SiN) wav…
Real-time surrogate modeling of nonlinear pulse evolution in multimode fibers
Bora Çarpınlıoğlu, Bahadır Utku Kesgin, Uğur Teğin
Modeling nonlinear pulse propagation in multimode fibers is challenging due to the large number of interacting modes and the resulting spatiotemporal complexity. Traditional optimi…
Controlling spatiotemporal nonlinearities in multimode fibers with deep neural networks
Uğur Teğin, Babak Rahmani, Eirini Kakkava +3
Spatiotemporal nonlinear interactions in multimode fibers are of interest for beam shaping and frequency conversion by exploiting the nonlinear propagation of different pump regime…
Competing Neural Networks for Robust Control of Nonlinear Systems
Babak Rahmani, Damien Loterie, Eirini Kakkava +4
The output of physical systems is often accessible by measurements such as the 3D position of a robotic arm actuated by many actuators or the speckle patterns formed by shining the…
