All-Optical Image Identification with Programmable Matrix Transformation
Shikang Li, Baohua Ni, Xue Feng +4
An optical neural network is proposed and demonstrated with programmable matrix transformation and nonlinear activation function of photodetection (square-law detection). Based on…

Universal linear optical operations on discrete phase-coherent spatial modes
Peng Zhao, Shikang Li, Xue Feng +5
Linear optical operations are fundamental and significant for both quantum mechanics and classical technologies. We demonstrate a non-cascaded approach to perform arbitrary unitary…

Identifying the tilt angle and correcting the orbital angular momentum spectrum dispersion of misaligned light beam
Peng Zhao, Shikang Li, Yu Wang +5
The axis tilt of light beam in optical system would introduce the dispersion of orbital angular momentum (OAM) spectrum. To deal with it, a two-step method is proposed and demonstr…
