Abstract

A specific case of a four-order non-collinear light scattering in anisotropic media is presented.Compared to our previous studies, an innovation lies in the fact that now we consider passing just the quartet of incident light waves through a single crystal that is perturbed by a coherent stream of acoustic phonons.The exact and closed analytical model for describing this strongly nonlinear phenomenon is developed.In fact, a specially designed regime of a four-order light scattering, when transitions of four input light beams into four output light modes are allowed and electronically controlled, is examined.The feasibility of applying such an effect to perform an all-optical switching is analyzed.An opportunity for arranging the digital 4-bit register is revealed and algorithmically analyzed.

All-optical switching and logic based on a two-phonon light scattering

Alexandre S. Shcherbakov, Eduardo Tepichín-Rodríguez

We consider physical principles of a two-phonon light scattering in crystals in a special case, when direct transitions between all the orders of scattering are allowed and, moreover, the probabilities of these transitions can be regulated electronically. The exact and closed analytical model for describing this process is presented. The feasibility of exploiting such a phenomenon for creation of an all-optical logic is substantiated. A few possibilities of arranging the optical logic gates are revealed. Fulfilling a set of logic operations is algorithmically analyzed and estimated.

Coherent control of electron-phonon scattering and the dephasing process in GaAs multiple quantum wells

Yoshihiro Ogawa, F. Minami

We show the coherent control of the non-Markovian oscillation of exciton-folded acoustic phonon scattering in GaAs multiple quantum wells by using four-wave mixing measurements. The extent of non-Markovian scattering depends on the delay time ${t}_{{1}^{\ensuremath{'}}1}$ between the phase-locked pulses. The phenomenological dephasing time in the long-time (Markovian) region does not depend on the scattering. The dephasing process is suppressed when ${t}_{{1}^{\ensuremath{'}}1}$ corresponds to half the period of the non-Markovian oscillation. The dephasing suppression is the result of a fifth-order nonlinear optical effect (a six-wave mixing process).

Coherently refreshed acoustic phonons for extended light storage

Birgit Stiller, Moritz Merklein, Christian Wolff +4 more

Acoustic waves can serve as memory for optical information, however, acoustic phonons in the GHz regime decay on the nanosecond timescale. Usually this is dominated by intrinsic acoustic loss due to inelastic scattering of the acoustic waves and thermal phonons. Here we show a way to counteract the intrinsic acoustic decay of the phonons in a waveguide by resonantly reinforcing the acoustic wave via synchronized optical pulses. This scheme overcomes the previous constraints of phonon-based optical signal processing for light storage and memory. We experimentally demonstrate on-chip storage up to 40 ns, four times the intrinsic acoustic lifetime in the waveguide. We confirm the coherence of the scheme by detecting the phase of the delayed optical signal after 40 ns using homodyne detection. Through theoretical considerations we anticipate that this concept allows for storage times up to microseconds within realistic experimental limitations while maintaining a GHz bandwidth of the optical signal. The refreshed phonon-based light storage removes the usual bandwidth-delay product limitations of e.g. slow-light schemes.

Crosstalk-free multi-wavelength coherent light storage via Brillouin interaction

Birgit Stiller, Moritz Merklein, Khu T. Vu +4 more

Stimulated Brillouin scattering drives a coherent interaction between optical signals and acoustic phonons and this effect can be used for storing optical information in acoustic waves. An important consideration arises when multiple optical frequencies are simultaneously employed in the Brillouin process: in this case the acoustic phonons that are addressed by each optical wavelength can be separated by frequencies far smaller than the acoustic phonon linewidth, potentially leading to crosstalk between the optical modes. Here we extend the concept of Brillouin-based light storage to multiple wavelength channels. We experimentally and theoretically show that the accumulated phase mismatch over the length of the spatially extended phonons allows each optical wavelength channel to address a distinct phonon mode, ensuring negligible crosstalk, even if the phonons overlap in frequency. Moreover, we demonstrate that the strict phase matching condition enables the preservation of the coherence of the opto-acoustic transfer at closely spaced multiple acoustic frequencies. This particular phase-mismatch for broad-bandwidth pulses has far-reaching implications allowing dense wavelength multiplexing in Brillouin-based light storage, multi-frequency Brillouin sensing, multi-wavelength Brillouin lasers, parallel microwave processing and quantum photon-phonon interactions.
