Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

Laser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

A Scalable Platform for Massively Parallel Superconducting Single‐Photon Detection

Laser &Photonics Reviews, EarlyView.
One hundred independent superconducting nanowire detectors, each with efficiency up to 80.1–98.3%, are integrated into a single compact system operating below 2.1 K. This parallel architecture supports fully connected multi‐user quantum entanglement distribution, while its scalability opens new avenues in optical quantum computing, QKD networks ...

Low‐Crosstalk Silicon Photonic Switch Fabrics for AI Datacenters and High‐Capacity Optical Interconnects: Device‐Level Origins and Mitigation

Laser &Photonics Reviews, EarlyView.
Scaling silicon photonic switch fabrics for AI datacenters is fundamentally constrained by accumulated crosstalk, insertion loss, and device‐level non‐idealities. This work establishes a device‐to‐link‐to‐system framework that connects the physical origins of crosstalk to practical mitigation strategies across device, circuit, and control levels.
