Variational framework for partially-measured physical system control: examples of vision neuroscience and optical random media

Babak Rahmani, Demetri Psaltis, Christophe Moser

To characterize a physical system to behave as desired, either its underlying governing rules must be known a priori or the system itself be accurately measured. The complexity of…

All-fiber spatiotemporally mode-locked laser with multimode fiber-based filtering

Uğur Teğin, Babak Rahmani, Eirini Kakkava +2

We demonstrate the first multimode fiber interference-based filtering in an all-fiber spatiotemporally mode-locked laser. The oscillator generates dissipative soliton pulses at 103…

Single mode output by controlling the spatiotemporal nonlinearities in mode-locked femtosecond multimode fiber lasers

Uğur Teğin, Babak Rahmani, Eirini Kakkava +2

The performance of fiber mode-locked lasers is limited due to the high nonlinearity induced by the spatial confinement of the single-mode fiber core. To massively increase the puls…

Wide-Band/Angle Blazed Dual Mode Metallic Groove Gratings

Omid Hemmatyar, Mohammad Ali Abbassi, Babak Rahmani +2

We introduce a new and simple approach to acquire wide-band/angle blazing operation in one-dimensional metallic gratings supported by equivalent circuit analysis. The gratings that…

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…
