Quantum-correlation-based free-space optical link with an active reflector

Dong‐Kyu Kim, Dohoon Lim, Kyungdeuk Park +1 more

We present a quantum-correlation-based free-space optical(FSO) link over 250 m using an outdoor active reflector 125 m from the transceiver station. The performance of free-space optical communication can be significantly degraded by atmospheric turbulence effects, such as beam wander and signal fluctuations. We used a 660 nm tracking laser to reduce atmospheric effects, by analyzing the fast beam wander and slow temporal beam drift, using this information to correct the quantum channel alignment of the 810 nm signal photons. In this work, the active reflector consisted of a mirror, a 6-axis hexapod stage, and a long-range wireless bridge. The slow drift of the beam path due to outdoor temperature changes was steered and controlled using wireless optical feedback between the receiver units and the active reflector. Our work provides useful knowledge for improved control of beam paths in outdoor conditions, which can be developed to ensure high quality quantum information transfer in real-world scenarios, such as an unmanned FSO link for urban quantum communication or retro-reflective quantum communication links.

Secrecy Outage Performance in Free Space Optical Communication Links

Aanchal Gupta, Divya Dhawan, Neena Gupta

Free space optical (FSO) communication is widely used wireless type of communication, which is highly advantageous as it offers huge capacity, immunity to electromagnetic interference, and low deployment cost. FSO systems are vulnerable to eavesdropping attacks due to the miniaturization and lightweight of optical devices used for detection. Therefore, secure communication of FSO systems remains a challenging task. In order to overcome this problem, secrecy outage probability (SOP) is analyzed in this study. A system model is presented comprising a transmitter and receiver, Alice and Bob and a malicious eavesdropper, Eve. Simulation results are demonstrated which reveal that for a fixed value of Eve’s signal-to-noise ratio (SNR), the SOP decreases with increasing values of Bob’s SNR. In addition, it is shown that increasing the values of coupling parameter deteriorates the SOP performance.
