Abstract :
This work describes the measurement of the frequency response of the wavelength modulation in a laser diode, for application in a closed-loop interferometer. The wavelength modulation is derived by the measurement of the interferometric phase, while the frequency response is estimated by means of frequency-domain model identification techniques.
