A new plasmonic dual-drive modulator enables cost- and power-efficient short-reach communications at highest speed. The plasmonic device allows for a 4-fold reach extension to distances beyond 10 km. The plasmonic transmitter is based on a simple and low-cost direct-detection/on-off-keying implementation with a single-wavelength data rate of 100 Gbit/s. Requiring no digital signal processing (DSP) in the transmitter, and by reducing the DSP-complexity in the receiver by a factor of >10, this technology becomes an attractive solution for intra-datacenter communication.
