Demonstration of 100 Gbps coherent free-space optical communications at LEO tracking rates
Scientific Reports, 2022 Free-space optical communications are poised to alleviate the data-flow bottleneck experienced by spacecraft as traditional radio frequencies reach their practical limit. While enabling orders-of-magnitude gains in data rates, optical signals impose much

Encryption in phase space for classical coherent optical communications
Scientific Reports, 2023 Optical layer attacks on optical fiber communication networks are one of the weakest reinforced areas of the network, allowing attackers to overcome security software or firewalls when proper safeguards are not put into place.

Spin Laser Local Oscillators for Homodyne Detection in Coherent Optical Communications
Micromachines, 2021 We numerically investigate spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for local oscillators, which are based on an injection locking technique used in coherent optical communications.

10-Gb/s Long-Reach PON System With Low-Complexity Dispersion-Managed Coherent Receiver
IEEE Photonics Journal, 2015 We demonstrate 10-Gb/s transmission over more than 130 km of G.652 fiber using a simple directly modulated distributed feedback (DFB) laser and a new “chirp-managed” approach based on a low-complexity coherent receiver.
