Optically Powered WDM Signal Transmission System With Distributed Parametric Amplification

Self-powered system with wireless data transmission.

We demonstrate the first self-powered system driven by a nanogenerator (NG) that works wirelessly and independently for long-distance data transmission. The NG was made of a free cantilever beam that consisted of a five-layer structure: a flexible polymer substrate, ZnO nanowire textured films on its top and bottom surfaces, and electrodes on the surfaces. When it was strained to 0.12% at a str...

Wavelength Demultiplexer for Optically Amplified WDM Submarine Cable System

The wavelength demultiplexer, using cascaded optical fiber gratings and circulators, was proposed and developed for application to optically amplified wavelength-division multiplexing (WDM) submarine cable systems with 100GHz channel spacing. Our proposed demultiplexer cannot only achieve high wavelength selectivity, small excess loss and effective allocation of dispersion compensation fibers f...

Optically Powered Fiber Optic Sensors

Optically Powered Fiber Optic Sensors (OPFOS) combine the advantages of fiber optic and microelectronic technologies [1-12]. Fiber optic and partially Fiber Optic Sensors (FOS) offer advantages that are significant in the field of variety of industrial, military and medical applications. FOS are immune to electromagnetic interference (EMI), they have low thermal and mechanical inertia, and they...

Realization of Mixed WDM Transmission System

Asymmetric parametric amplification in nonlinear left-handed transmission lines

We study parametric amplification in nonlinear left-handed transmission lines, which serve as model systems for nonlinear negative-index metamaterials. We experimentally demonstrate the amplification of a weak signal in the three following regimes: with the signal in the left-handed band, with the signal in the stop band, and with the signal at a defect frequency. In particular, we demonstrate ...
