Abstract
Techniques for characterizing the response of an optical device comprising modulating at least one signal using the device; coupling the modulated signal with a reference signal in a variety of ways; detecting the coupled signals; and obtaining the response of the modulator by analyzing the detected signals, are described. In a heterodyne embodiment, the method includes modulating a first optical signal using the optical device to produce a modulated first optical signal, the modulated first optical signal is combined with a second optical signal in a different spectral region; and the response of the optical device is determined from the intensity of the combined optical signal. A homodyne method using various splitting and recombining of the modulated optical signal with a reference signal is also described.
