Enhancement of Second Harmonic Generation in Monolayer WS2 by Feedback-Based Wavefront Shaping
Russell Berger, Alex Mavian, Edgar Dimitrov +8
Two-dimensional Transition-Metal Dichalcogenides (TMDs) are of great interest for second harmonic (SH) generation due to their large second-order susceptibility, atomically thin st…
Classification of Single Photons in Higher-Order Spatial Modes via Convolutional Neural Networks
Manon P. Bart, Sita Dawanse, Nicholas J. Savino +7
Spatial modes are a promising candidate for encoding information for classical and quantum optical communication due to their potential high information capacity. Unfortunately, co…
On the Generation of Topological Vector Solitons from Bessel-Like Beams
Finn Buldt, Pascal Basséne, Moussa N'Gom
Coupled solitary waves in optics literature, are coined vector solitons to reflect their particle-like nature that remains intact even after mutual collisions. They are born from a…
Multiple feedback based wavefront shaping method to retrieve hidden signal
Nazifa Rumman, Tianhong Wang, Kaitlin Jennings +3
We present an optical wavefront shaping approach that allows tracking and localization of signal hidden inside or behind a scattering medium. The method combines traditional feedba…
Femtosecond Filament Coupled with Structured Light for Free Space Optical Communication
Saad Bin Ali Reza, Tianhong Wang, Finn Buldt +2
The generation of a laser filament through clouds produces a shockwave which displaces the small water droplets from the air to create a quasi-transparent channel through which, in…
On the Generation of Topological Vector Solitons from Bessel Like Beams
Finn Buldt, Pascal Bassène, Moussa N'Gom
Coupled solitary waves in optics literature, are coined vector solitons to reflect their particle--like nature that remains intact even after mutual collisions. They are born from…
Nonlinear Conversion of Orbital Angular Momentum States of Light
Pascal Bassène, Finn Buldt, Nazifa Rumman +3
We investigate the second harmonic generation of light field carrying orbital angular momentum in bulk material. We show that due to conservation of energy and momentum,…
Mode Control in a Multimode Fiber Through Acquiring its Transmission Matrix from a Reference-less Optical System
Moussa N'Gom, Theodore B. Norris, Eric Michielssen +1
A simple imaging system together with complex semidefinite programming is used to generate the transmission matrix of a multimode fiber. Once the transmission matrix is acquired, w…
Controlling Light Transmission Through Highly Scattering Media Using Semi-Definite Programming as a Phase Retrieval Computation Method
Moussa N'Gom, Miao-Bin Lien, Nooshin M. Estakhri +3
Complex Semi-Definite Programming (SDP) is introduced as a novel approach to phase retrieval enabled control of monochromatic light transmission through highly scattering media. In…
