“…The corresponding sampling frequency used as a control signal g(t) is 21 multiples of the fundamental frequency. In delay differential systems, we can design and generate arbitrary multi-valued waveforms (isomer signals) of higher periodic orders for the fundamental periodic oscillation by adding extra control circuits to the systems (Liu and Ohtsubo 1991;Liu et al 1994). In this example, the control signal is a very small perturbation to the chaotic oscillation and its amplitude is less than 3 % of the bias injection current.…”

On the way to chaotic evolution, periodicity, bistability, and multistability are observed, such as in the outputs of semiconductor lasers with optical feedback. The system of optical feedback in a semiconductor laser is sometimes called self-mixing semiconductor laser. In a periodic state, the laser output shows not simply periodic oscillation but also hysteresis. Novel applications have been proposed based on these phenomena, for example, a displacement measurement is performed by counting the fringes obtained from bistable self-mixing interference between the internal field and the optical feedback light in the laser cavity. The direction of the displacement is simultaneously determined from asymmetric waveforms showing hysteresis. Also correlation of signals between scattering and reference chaotic lights can be applied for remote sensing from distant reflecting targets. We discuss various methods for optical metrology based on self-mixing interference effects and correlation techniques in semiconductor lasers. This chapter does not deal with the detailed descriptions of the methods and their accuracies but with the introduction of the principles of the methods.

High-dimensional chaos was controlled with the occasional proportional feedback technique in a delayed optical bistable system which consists 0L a laser diode interferometer with a delayed opto-electronic feedback 100p. Both the experiment and the numerical simulation showed that a large number of periodic orbits can be stabilized by controlling the chaotic attractor. The transient state of the trajectory under control was demonstrated.
