1. A system for detecting changes in incident optical radiation at high frequencies, comprising:

  • a detector having one or more asymmetrically conductive active areas formed of relaxation semiconductor material;

    at least two electrical contacts configured with the detector and positioned with an active area therebetween; and

    electronics connected to the electrical contacts, for sensing a transient voltage across the active area, the transient voltage being indicative of the changes in incident optical radiation.
