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.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Black Phosphorus/Ferroelectric CuInP2S6 Heterostructures Empowering Nonvolatile Photonic Convolutional Computing

Laser &Photonics Reviews, EarlyView.
ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

Laser &Photonics Reviews, EarlyView.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

Materials and Corrosion, EarlyView.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.
