Coherence and contextuality in a Mach-Zehnder interferometer [PDF]

Quantum
We analyse nonclassical resources in interference phenomena using generalized noncontextuality inequalities and basis-independent coherence witnesses. We use recently proposed inequalities that witness both resources within the same framework.

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture

Laser &Photonics Reviews, EarlyView.
A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...

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 ...

Numerical analysis of DP-MZI–SI comb filter improvement using polarisation-maintaining fibre

Results in Physics, 2020
In this paper, we present a numerical analysis of a novel comb filter in a double-pass Mach–Zehnder interferometer and a Sagnac interferometer (DP-MZI–SI) configuration and verify it by partial experimental demonstration. The proposed filter comprises an

Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

Laser &Photonics Reviews, EarlyView.
Independent control of the repetition rate and offset frequency is demonstrated in quantum cascade laser frequency combs using radio‐frequency injection and thermal tuning. A revised comb model anchored at optical frequencies captures the unique behavior under radio‐frequency injection and enables precise frequency control.

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.

Programmable Multidimensional Diffraction Engineering via an Optically Addressed Nested Fourier Metasurface

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
An optically addressed nested Fourier metasurface is presented for programmable multidimensional diffraction routing without electrical interconnects. Local Fourier‐mode engineering combined with global superlattice diffraction enables on‐demand reconfigurable routing.

Turning Light Into Matter: Programmable Microstructures Via Dose Control in Two‐Photon Polymerization

Advanced Optical Materials, Volume 14, Issue 37, 9 October 2026.
This work augments two‐photon polymerization with point‐wise dose control, enabling structures with heterogeneous material properties such as refractive index. An open source toolbox and superior calibration methodology for the refractive index pave the way for bio‐mimicking or numerically optimized structure designs, and enhance the synergy between 3D
