Compact Fourier‐Transform Spectrometer on Thin‐Film Lithium Niobate via Mode‐Circulating Modulation

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Schematic diagram of the proposed compact on‐chip Fourier‐transform spectrometer on thin‐film lithium niobate that exploits mode‐circulating electro‐optic modulation, in which guided light is sequentially converted among multiple spatial modes to accumulate multiple phase modulation events within a single physical modulation arm.

Imaging fibre bundles for Fizeau-based optical coherence tomography [PDF]

, 2008
An OCT system incorporating a coherent fibre imaging bundle is described. Fibres are accessed sequentially by a beam focused onto the input face of the bundle, allowing 2D or 3D images to be acquired using point detection.

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era

Annalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.

Gravitational Radiation From Binary Systems With Time Varying Masses

Annalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Waveform modelling for the Laser Interferometer Space Antenna

Living Reviews in Relativity
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will expand our view to the millihertz gravitational-wave sky, where a spectacular

On-sky Demonstration of Subdiffraction-limited Astronomical Measurement Using a Photonic Lantern

The Astrophysical Journal Letters
Resolving fine details of astronomical objects provides critical insights into their underlying physical processes. This drives in part the desire to construct ever-larger telescopes and interferometer arrays and to observe at shorter wavelengths to ...
