Intel recently announced a display of some new technology which looks like another step along the way to a good proof of concept of efficient wireless electricity. Building on Marin Soljacic’s work at MIT (it’s unclear to me whether Intel is actually building on top of the work of Marin’s group or if they’re working in parallel) the group from Intel is displaying the transfer of energy without wires from a transmitter to a receiver separated only by air which in result lights a light bulb. Intel’s demonstration was covered by Gizmodo and has a nice description and some great pictures.

“Abstract—The silicon evanescent device platform provides electrically pumped active device functionality on a low-loss siliconon-insulator waveguide platform.We present here recent research in the area of single-wavelength silicon evanescent lasers that utilize distributed feedback, distributed Bragg reflector (DBR), and sampled grating (SG) DBR laser topographies.”

Abstract: Data amplification using hybrid silicon evanescent amplifier is demonstrated at bit rates up to 40Gbps. The amplifier exhibits 13dB on-chip gain with low power penalty of 0.5dB. Pattern effects due to carrier lifetime are investigated. ©2007 Optical Society of America

Recently hybrid integration of III-V semiconductors onto silicon waveguides with wafer bonding technology [1] was demonstrated. Silicon based amplifiers are important for many silicon photonic integrated circuits (PICs). Onchip evanescent amplifiers can be used as a post-amplifier for the silicon evanescent laser [2] or integrated as a preamplifier with waveguide photodetectors. In the case of pre-amplification, dynamic characteristics and power penalty are important for high speed data detection. An electrically pumped hybrid amplifier was fabricated and tested with bit error rate (BER) measurement. The device exhibits 13dB on-chip gain and only 0.5dB power penalty for data rates up to 40Gbps.
