Experimental Evaluation of the Impact of Turbulence on a Time-Bin and Phase QKD System

The time-bin and phase bases for quantum key distribution (QKD) schemes have been explored as an alternative to polarization bases to overcome the challenge of optical fiber birefringence. However, in free-space, turbulence introduces perturbations in the optical phase and path-length that might influence the performan...

Scintillation Analysis of a 400-Gb/s Coherent FSO Feeder-Link for GEO Satellite Downlink-Like Transmission

In this letter, we experimentally demonstrate 400 Gbps coherent transmission over a turbulent free-space optical (FSO) channel for optical feeder links using a commercially available fiber-optimized coherent transponder. Controlled atmospheric turbulence (AT) with a refractive-index structure parameter up to $C_{n}^{2}...

Digital Twin Orchestrated Software-Defined Networks for Handling Denial of Service Attacks in IoT Applications

The paper discusses the implementation and analysis of a digital-twin-orchestrated preemptive-switching scenario for sensor-data transmission over physical network interface links. The experimental setup in this work uses physical interface connections based on radio and optical interfaces, defined by the standards of...
