Lab-on-Chip Acoustic Detection Platform: Design, Fabrication and Performance Evaluation

Makrem Ben Abdelkader, Hatem Dahmani, Reda Aitayad, Samuel Dupont, Chérif Dridi, Julien Carlier

The growing demand for compact and high- sensitivity analytical platforms has accelerated the integration of micro-electro-mechanical systems (MEMS) with acoustic and microfluidic technologies. However, conventional sensors still face challenges in terms of miniaturization, fabrication cost, and…

Integrated 3 GHz Bandwidth Optical Modulator Operating in the 5-9 µm Wavelength Range

Javier Huertas Pedroche, Victor Turpaud, Luca Lucia, Adel Bousseksou, Hamza Dely, Gia Long Ngo, Stefano Calcaterra, Davide Impelluso, Afonso de Cerdeira Oliveira, Victor Merupo, Emilien Peytavit, Jean-François Lampin, Stefano Barbieri, Jacopo Frigerio, Raffaele Colombelli, Giovanni Isella, Delphine Marris-Morini

A compact electro-optic modulator integrated within a SiGe waveguide operating in the 5−9μm wavelength range is demonstrated. Utilizing a Schottky diode and freecarrier absorption effect, the device achieves at least 3GHz bandwidth and an ER of 1.75∼dB.

Waveguide-pair design co-optimization and tolerance study for hybrid III-V/Si quantum dot DBR lasers

Konstantinos Papatryfonos, Peter Raymond Smith, David Selviah

<div><p>The development of compact, energy-efficient integrated lasers operating at 1.3 µm remains a central goal in silicon photonics, driven by the needs of data communication and optical interconnect applications. In this study, we investigate the lateral co-optimization of the…

Low-defect quantum dot lasers directly grown on silicon analyzed using cross-sectional scanning tunneling microscopy and spectroscopy

Konstantinos Papatryfonos, Jean-Christophe Girard, Mingchu Tang, Christophe David, Alwyn Seeds, Guillemin Rodary, Huiyun Liu, David Selviah

<div><p>Monolithic integration of III-V lasers on silicon is a central objective of silicon photonics, yet direct heteroepitaxy remains challenged by lattice and thermal-expansion mismatches that generate dislocations and other extended defects. Here we report an optimized molecular…

Fundamental thermovisco mechanical interactions governing the acoustic response of laser-excited nanoparticles

Stefano Giordano, Michele Diego, Francesco Banfi, Michele Brun

In this work, we investigate the thermoacoustic generation and propagation of spherical waves in a viscous fluid induced by a laser-heated spherical particle. Periodic laser excitation gives rise to two coupled mechanisms of acoustic emission. Heat transfer from the particle to the surrounding…

Coexistence and interplay of Fabry–Pérot and twin Friedrich–Wintgen bound states in the continuum in a plasmonic double T-cavity

Amina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are typically investigated in terms of distinct formation mechanisms, such as symmetry-protected (SP), Friedrich–Wintgen (FW), or Fabry–Pérot (FP) BICs. However, their coexistence and mutual interaction within a single plasmonic architecture have not been…
