“…method provides an interpretation of experiments achieved in the time domain with ultrasonic pulses, where it is shown that the back emitted timereversed scattered wave focuses on the bright points responsible for diffraction. The set of transducers is called "time reversal mirror" [Fink et al, 1989], and extends to transient waves the phase conjugation mirrors known in Optics [Pepper, 1982]. Basically, the D.O.R.T.…”

[1] The decomposition of the time reversal operator (D.O.R.T.) method allows detection and localization of point-like scatterers through a very simple and robust process. Here, with the aim of applying this method to the detection and the localization of buried objects, we focus on the influence of the restriction of the measurements to a line of receivers. The finite size of the objects is also taken into account, as well as losses in the embedding medium. A simple behavior of the time reversal operator is exhibited, almost independent of the polarization, which permits one to detect scatterers in the resonance domain, with very low ambiguity. Experimental data obtained in an anechoïc chamber confirm our theoretical predictions.

“…One of the most popular types of an unconventional mirror is the phase conjugation mirror (PCM) [1]. The PCM conjugates the phase on the mirror surface, and causes the reflected light to rewind through the path that the input light has travelled.…”

Rewinding the arrow of time via phase conjugation is an intriguing phenomenon made possible by the wave property of light. Here, we demonstrate the realization of a one-wave optical phase conjugation mirror using a spatial light modulator. An adaptable single-mode filter is created, and a phase-conjugate beam is then prepared by reverse propagation through this filter. Our method is simple, alignment free, and fast while allowing high power throughput in the time-reversed wave, which has not been simultaneously demonstrated before. Using our method, we demonstrate high throughput full-field light delivery through highly scattering biological tissue and multimode fibers, even for quantum dot fluorescence.

“…10,11 Among the various experimental DFWM schemes suitable to satisfy the phase-matching condition for efficient signal generation, the forward setup (FDFWM) is preferable when a high spatial resolution is required and weak signals have to be recorded. In FDFWM, three beams (one weak probe and two strong pump beams) at the same frequency and polarization state are initially arranged to travel along three of four corners of a square.…”

We have investigated the third order nonlinear optical properties of carbon nanotubes thick films. Nanosecond Degenerate Four Wave Mixing (DFWM) measurements have been performed at 532 and 355 nm yielding effective c .3/ values of the order of 10 −11 esu. and indicating the resonant nature of the excitation involved. The determination of the CNTs sample density by means of Scanning Electronic Microscope technique allowed to relate sample bulk properties like c .3/ to the single CNT second order polarizability coefficient.
