“…In this work, we integrate fibered systems to eliminate any optical alignment on the sample, thus simultaneously solving the three aforementioned main problems. We glued single mode fibers to a planar optophononic microcavity and to an optophononic micropillar [6,[19][20][21][25][26][27][28]. The integration with fibers might establish the missing link between high frequency acoustic phonon engineering [29][30][31][32][33] and stimulated Brillouin scattering in structured optical fibers [34][35][36][37][38].…”

Coherent phonon generation by optical pump-probe experiments has enabled the study of acoustic properties at the nanoscale in planar heterostructures, plasmonic resonators, micropillars and nanowires. Focalizing both pump and probe on the same spot of the sample is a critical part of pumpprobe experiments. This is particularly relevant in the case of small objects. The main practical challenges for the actual implementation of this technique are: stability of the spatio-temporal overlap, reproducibility of the focalization and optical mode matching conditions. In this work, we solve these three challenges for the case of planar and micropillar optophononic cavities. We integrate the studied samples to single mode fibers lifting the need for focusing optics to excite and detect coherent acoustic phonons. The resulting excellent reflectivity contrast of at least 66% achieved in our samples allows us to observe stable coherent phonon signals over at least a full day and signals at extremely low excitation powers of 1µW. The monolithic sample structure is transportable and could provide a means to perform reproducible plug-and-play experiments.

“…The magnitude of this trapenhanced optomechanical coupling decreases as the order of the involved optical modes increases. As we will argue below, the optomechanical coupling scales as 1/D, where D is the lateral diameter of the involved trap-confined mode 28,29 . Because of the Gaussian shape of the laserinduced optical trap 4 , modes are laterally less confined as their order increases.…”

“…Namely, i) it does not require technologically complex techniques of device microfabrication, ii) the laser-engineered potentials can be dynamically modified on demand, and iii) microstructured lateral edges are avoided, which are known to be limiting factors for both the photon and phonon lifetimes for microstructures with lateral size below a few microns. 28,29 Disadvantages are the requirement of a laser for the establishment of the lateral potential, and the eventual related heating associated to the latter.…”

Laser engineered exciton-polariton networks could lead to dynamically configurable integrated optical circuitry and quantum devices. Combining cavity optomechanics with electrodynamics in laser configurable hybrid designs constitutes a platform for the vibrational control, conversion, and transport of signals. With this aim we investigate 3D optical traps laser-induced in quantum-well embedded semiconductor planar microcavities. We show that the laser generated and controlled discrete states of the traps dramatically modify the interaction between photons and phonons confined in the resonators, accessing through coupling of photoelastic origin g0/2π ∼1.7 MHz an optomechanical cooperativity C > 1 for mW excitation. The quenching of Stokes processes and double-resonant enhancement of anti-Stokes ones involving pairs of discrete optical states in the side-band resolved regime, allows the optomechanical cooling of 180 GHz bulk acoustic waves, starting from room temperature down to ∼120 K. These results pave the way for dynamical tailoring of optomechanical actuation in the extremely-high-frequency range (30-300 GHz) for future network and quantum technologies.

Phonon engineering with superlattices: Generalized nanomechanical potentials

Earlier implementations to simulate coherent wave propagation in one-dimensional potentials using acoustic phonons with gigahertz-terahertz frequencies were based on coupled nanoacoustic resonators. Here, we generalize the concept of adiabatic tuning of periodic superlattices for the implementation of effective one-dimensional potentials giving access to cases that cannot be realized by previously reported phonon engineering approaches, in particular the acoustic simulation of electrons and holes in a quantum well or a double well potential. In addition, the resulting structures are much more compact and hence experimentally feasible. We demonstrate that potential landscapes can be tailored with great versatility in these multilayered devices, apply this general method to the cases of parabolic, Morse and double-well potentials and study the resulting stationary phonon modes. The phonon cavities and potentials presented in this work could be probed by all-optical techniques like pump-probe coherent phonon generation and Brillouin scattering.
