Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

An Epsilon‐Near‐Zero‐Based Nonlinear Platform for Ultrafast Re‐Writable Holography

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
We show that an unstructured, sub‐wavelength thick epsilon‐near‐zero material, such as ITO, can be efficiently used for ultrafast re‐writable holography over a broad bandwidth range. We showcase two powerful applications of our scheme, that is, spatial structuring of light and optical computation.
