Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication

Laser &Photonics Reviews, EarlyView.
A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Reversible Thermal Tuning of High‐Q Non‐Local Lithium Niobate Metasurfaces

Laser &Photonics Reviews, EarlyView.
Introducing a polarization sensor using scattering in a short optical fiber and deep learning. The breakthrough lies in sparse sampling of the scattered light and single‐photon sensitivity. The all‐fiber sensor achieves unprecedented accuracy, speed, resolution, and stability.

Long-period waveguide gratings

Proceedings of the Sixth Chinese Optoelectronics Symposium (IEEE Cat. No.03EX701), 2004
Long period waveguide gratings (LPWG) based on a low-loss negative tone epoxy Novolak resin polymer have been fabricated on SiO/sub 2//Si substrate using standard cleanroom processes: UV photolithography and reactive ion etching. A maximum attenuation of -18 dB and a minimum 3 dB bandwidth of 6 nm were measured, and the grating length is as short as 1 ...
