Net 835-Gb/s/λ Carrier- and LO-Free 100-km Transmission Using Channel-Aware Phase Retrieval Reception
We experimentally demonstrate the first carrier- and LO-free 800G/{\lambda} receiver enabling direct compatibility with standard coherent transmitters via phase retrieval, achieving net 835-Gb/s transmission over 100-km SMF and record 8. 27-b/s/Hz net optical spectral efficiency.
Distortion-Aware Phase Retrieval Receiver for High-Order QAM Transmission with Carrierless Intensity-Only Measurements
We experimentally investigate transmitting high-order quadrature amplitude modulation (QAM) signals with carrierless and intensity-only measurements with phase retrieval (PR) receiving techniques.
Real-time Optical Network Sensing Control Plane Enabled by a Novel Sub us Response Time Fibre Sensing Control Device
We propose and implement a novel fibre sensing control device and associated sensing control plane that effectively controls backscatter and polarization-based fibre sensing.
Real-Time Monitoring of Cable Break in a Live Fiber Network using a Coherent Transceiver Prototype
We monitor a 524km live network link using an FPGA-based sensing-capable coherent transceiver prototype during a human-caused cable break.
Advanced Distributed Submarine Cable Monitoring and Environmental Sensing using Constant Power Probe Signals and Coherent Detection
In this work we demonstrate an FPGA-based coherent optical frequency domain reflectometry setup for cable monitoring.
Transoceanic Phase and Polarization Fiber Sensing using Real-Time Coherent Transceiver
We implement a real-time coherent transceiver with fast streaming outputs for environmental sensing.
Power Efficient Communication for Low Signal to Noise Ratio Optical Links
Receiver sensitivity is a particularly important metric in optical communication links operating at low signal-to-noise ratios (SNRs), for example in deep-space communication, since it directly limits the maximum achievable reach and data rate.
Digital Interference Mitigation in Space Division Multiplexing Self-Homodyne Coherent Detection
We propose a digital interference mitigation scheme to reduce the impact of mode coupling in space division multiplexing self-homodyne coherent detection and experimentally verify its effectiveness in 240-Gbps mode-multiplexed transmission over 3-mode multimode fiber.
Exploiting Angular Multiplexing for Polarization-diversity in Off-axis Digital Holography
Digital holography measures the complex optical field and transfer matrix of a device, polarization-diversity is often achieved through spatial multiplexing.
