Development of backing piezoelectric micromachined ultrasonic transducer (B-PMUT) 2D array

Xu-Bo Wang, You-Cao Ma, Le-Ming He, Yan Wang, Wei-Jiang Xu, Antoine Riaud, Jun-Yan Ren, Jia Zhou

To improve the problem of narrow bandwidth and large crosstalk in high-frequency PMUT array, a PMUT device with a damping backing structure (B-PMUT) is proposed and realized. The device is a two-dimensional array of 8×16 elements with an element pitch of 75 µm. The results show that the bandwidth…

Y-shaped demultiplexer photonic circuits based on detuned stubs: application to radiofrequency domain

Abdelkader Mouadili, Soufyane Khattou, Madiha Amrani, El Houssaine El Boudouti, Noureddine Fettouhi, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a theoretical and experimental study of photonic demultiplexers based on detuned stubs. The demultiplexers consist of Y-shaped structures with one input line and two output lines. Two different types of structures are proposed to achieve a selective transfer of a single mode in one…

Détecteur infrarouge hétérodyne à cascade quantique, Quantum cascade infrared heterodyne detector

Grégory Quinchard

La gamme spectrale du moyen infrarouge (MIR : 3-12 μm) s’ouvre aujourd’hui à de nouvelles possibilités d’applications grâce à la maturité des lasers à cascade quantique : communications espace libre, spectroscopie, LIDAR... Or, il n’existe aujourd’hui pas de détecteur rapide fonctionnant à…, The mid-infrared spectral range (MIR: 3-12 μm) is now opening up to new application possibilities thanks to the maturity of quantum cascade lasers: free-space communications, spectroscopy, LIDAR... However, there is currently no fast detector operating at room temperature in this spectral range:…

Fano resonance between stokes and anti-stokes Brillouin scattering

Kwanto Lai, Daniel Finkelstein-Shapiro, Sebastian Lehmann, Arnaud Devos, Pierre-Adrien Mante

In recent years, the manipulation of Fano resonances in the time domain has unlocked deep insights into a broad spectrum of systems’ coherent dynamics. Here, inelastic scattering of light with coherent acoustic phonons is harnessed to achieve complex Fano resonances. The sudden change of phonon…

Stochastic Resource Optimization of Random Access for Transmitters with Correlated Activation

Ce Zheng, Malcolm Egan, Laurent Clavier, Anders E Kalør, Petar Popovski

For a range of scenarios arising in sensor networks, control and edge computing, communication is event-triggered; that is, in response to the environment of the communicating devices. A key feature of device activity in this setting is correlation, which is particularly relevant for sensing of…
