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 ...

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

Laser &Photonics Reviews, EarlyView.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

512‐Fold Rotational Super‐Resolution via Four‐Photon High‐Dimensional Structured Light

Laser &Photonics Reviews, EarlyView.
A quantum rotation sensor that combines four photon states and high dimensional structured light ‐ characterized by a topological charge of 128 ‐ demonstrates a 512‐fold angular super‐resolution. ABSTRACT Structured light enhances quantum information processing by combining quantum states of light and shaped wavefronts.

3D Surface Profiling via Direct End‐to‐End Regression With a Photonic Geometric Sensor

Laser &Photonics Reviews, EarlyView.
Measurements of microscale surface patterns are essential for quality control across semiconductor and biomedical industries, yet the development of miniaturized, intelligent systems remains constrained by the complexity and bulkiness of conventional benchtop metrology.

Mode‐Locked Pulse Generation in Plasmonic Lattices

Laser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

Laser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Mid‐Infrared Quantum Scanning Microscopy via Visible Light Beyond Spatial Correlations

Laser &Photonics Reviews, EarlyView.
This work introduces a raster‐scanning approach based on quantum imaging with undetected light (QIUL) that probes samples in the mid‐infrared (MIR) spectral range while performing detection in the visible domain. Unlike previous QIUL implementations, this technique operates independently of photon‐pair spatial correlations and relies solely on induced ...
