Meta-optical processors for broadband complex-field image operations
Linzhi Yu, Jesse Pietila, Haobijam J. Singh +2
All-optical image processing provides a fast and energy-efficient alternative to conventional electronic systems by directly manipulating optical wavefronts. However, metasurface-b…
Analytical Framework of Orbital Angular Momentum Beam under Misaligned Detection
Arttu Nieminen, Rizwana Ahmad, Harald Haas +1
This work presents an analytical framework for modeling a detected orbital angular momentum (OAM) spectrum of an optical beam subject to tilt and lateral displacement. Firstly, we…
Harmonic generation in bent graphene with artificially-enhanced spin-orbit coupling
Arttu Nieminen, Marco Ornigotti
We theoretically investigate the nonlinear response of bent graphene, in the presence of artificially-enhanced spin-orbit coupling, which can occur either via adatom deposition, or…
Goos-Hänchen and Imbert-Fedorov Shifts for Epsilon-Near-Zero Materials
Arttu Nieminen, Andrea marini, Marco Ornigotti
We investigate the reflection of a Gaussian beam impinging upon the surface of an epsilon-near-zero (ENZ) medium. In particular, we discuss the occurrence of Goos-Hänchen and Imber…
Efficient differentially private learning improves drug sensitivity prediction
Antti Honkela, Mrinal Das, Arttu Nieminen +2
Users of a personalised recommendation system face a dilemma: recommendations can be improved by learning from data, but only if the other users are willing to share their private…
