Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication
Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.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 ...

Multiplexing Two Types of High‐Order Topological Corner States in Kagome Lattice Photonic Crystals
Nanophotonics, Volume 15, Issue 8, 24 April 2026.Higher‐order topological corner states in kagome photonic crystals exhibit a direction‐wavelength locking mechanism: two corner states with distinct resonant frequencies couple to different output channels. Harnessing this effect, a 1 × 2 wavelength demultiplexer achieves low‐crosstalk signal separation, demonstrating the potential of topological ...
