Abstract
The present invention relates to a device for both-way transposition between optical signals and electrical signals, for a communications system, said device comprising a vertically integrated component comprising an optically driven oscillator based on a negative differential conductance mechanism, for performing optical-to-millimetric conversion on the down path, and an asymmetric Fabry-Perot cavity modulator for performing the electrical-to-optical conversion function on the up path.
