Abstract

A simple noniterative electric field retrieval method using a sinusoidally driven optical phase modulator is demonstrated. We derive an analytic relation between the two-frequency correlation function of the electric field of the optical signal under test and the derivatives of the optical spectrum of the phase-modulated signal with respect to the amplitude of the phase modulation. This relation is used to algebraically reconstruct the electric field of the signal under test. We validate the technique by demonstrating accurate and sensitive characterization of picosecond pulses used in telecommunication.
