#406 Photonic alternative

In another solution, electron as an information carrier is replaced by the photon, representing quantum of light. Photon is more efficient than electron information carrier as it can cover distances in the waveguides with very little losses, which is in stark contrast to electron moving in semiconductors and metals with significant losses.


With short wavelength laser diodes and detectors available, and optical waveguides technology being well develop, a still missing link in this “all photonics” scenario is a high-performance optical transistor needed to turn light “on” and “off”.
