Multicolor Transceiver for Optoelectronic Communication

A great increase in the effectiveness of fiber optic systems is possible with a device that allows for simultaneous two-way signalling of multiple data streams on a single optical fiber. By using a highly efficient multijunction solar cell to emit as well as detect two or more distinct wavelengths within a broad band of near-infrared (0.93-1.65-micron) light, this new technology provides such a capability and many others.
