Abstract
Systems and methods for generating an electrical copy of an optical signal without having to terminate the optical signal. In one embodiment, an optical amplifier is configured to receive the optical signal and to allow the optical signal to pass therethrough. The optical amplifier is “pumped” by applying a bias voltage across it. The optical signal passing through the optical amplifier causes a population inversion within the optical amplifier to alternately collapse and recharge. A resistor is placed in series with the optical amplifier so that the bias current through the optical amplifier generates a voltage across the resistor which mirrors the optical signal. Both the optical signal and the electrical signal are provided as outputs.
