Abstract

The transient of a self-mixing interferometry (SMI) sensing system is investigated in this paper by solving the well known Lang and Kobayashi (LK) equations. Specifically, the influence of two important system parameters, i.e., the feedback level factor and the linewidth enhancement factor, on the transient is discussed, showing that the decay time and the oscillation period of the transient respectively increases and decreases with the increase of the feedback level factor, and both increase with the increase of linewidth enhancement factor. The results presented in this paper are useful for designing a stable SMI system.
