Laser &Photonics Reviews, EarlyView.A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Modelling System Parameters for Improvised Performance in Free Space Optics (FSO) Networks
International Journal of Electrical and Electronics Research, 2023 Free space optics (FSO) is a remote method for correspondence that send information by means of an optical source. The medium among transmitter and recipient is a free space that has an away from of sight for imparting the sign. Air, vacuum, and space can go about as free space.

FSO Detection using differential signaling in outdoor correlated-channels condition [PDF]
, 2016 In this letter, we introduce a detection technique based on differential signaling scheme for outdoor free space optical communications. This method requires no channel state information (CSI) and does not suffer from the computational load compared with

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.
