1. A system for polishing an optical fiber with a polishing lap, comprising:

  • a substrate;

    an elongate optical fiber disposed on the substrate so as to be outwardly curved;

    an electrical conductor disposed over the outward curve of the optical fiber;

    a voltage source connected to the electrical conductor for supplying a voltage thereto;

    wherein the polishing lap is configured to initially abrade the electrical conductor to cause severance thereof, the position of the polishing lap when the electrical conductor is severed representing a reference point relative to the surface of the optical fiber;

    a detector configured for detecting a change in voltage in the electrical conductor, said change being indicative of the severance of the electrical conductor, and for monitoring the polishing depth relative to the reference point.
