Abstract

In an embodiment a includes providing the self-mixing interferometer including a laser diode, emitting laser light and receiving a reflected portion of the emitted laser light to modulate an optical power of the laser diode, the interferometer having a transfer function of the optical power of the laser diode having fringes, locking a phase of the laser light to at least one of the fringes to obtain an operating point, generating an interrogation signal to change a wavelength of the laser light to obtain a response signal indicative of an offset of the operating point from a desired operating point and generating a compensation signal depending on the response signal.
