Abstract: The present application is directed to the measurement of the intensity and phase of high speed optical signals. The present application uses a tunable optical local oscillator, an optical coupler, a photodiode and RF electronics. The tunable laser enables successive measurements to be taken across the optical spectrum allowing the system to measure extremely high bandwidth signals. The signal generated by the local oscillator comprises a component at a frequency between two adjacent modes of the periodic optical signal to be measured. The local oscillator and said periodic signal are optically mixed and sent to a photodiode, the measurement of the phase being based on isolating the resulting beat frequencies. This approach offers a significant improvement over existing time resolved approaches which are limited to the bandwidth of the photodiode (˜50 GHz).
