In-situ dispersion measurement of a coupled optoelectronic oscillator

We present a direct measurement of the intracavity dispersion of a coupled optoelectronic oscillator (COEO). The measurement can be performed while the COEO is oscillating, taking into account the dispersion of the modulator and the saturated active medium, without any other component than the ones composing the oscillator. It eases the dispersion management before the detection stage for minimal amplitude-to-phase noise coupling.
