Two-Pump Distributed Parametric Amplification for Optically Powered Communication System
Fiber optics amplifiers oscillators Nonlinear optics parametric processes
2011/5/25
We demonstrate a power-efficient two-pump distributed parametric amplification(DPA) system. The residual pumps are recycled to power up the receiving component. At the BER of 10 −9 , power penal...
Energy-efficient MAC Protocol Enabling an Optically Powered Sensor Network
Energy-efficient MAC Protocol Optically Powered Sensor Network
2011/5/18
A new MAC protocol allows communication with both awake and asleep network elements. The protocol and its capabilities are demonstrated in an exemplary sensor network.
Optically Powered Low-Energy Demarcation Device for Monitoring FTTx Networks
Fiber optics optical communications Remote sensing sensors
2010/6/5
We demonstrate an energy-autarkic FTTx monitor. A special protocol and sophisti-cated hardware reduce the electrical operating power to 0.7μW, which can be delivered by an optical supply signal of onl...
