Narrow linewidth generation at 1 THz using cascaded Brillouin fiber lasers and quasi-optic UTC-PD

Guillaume Ducournau, Denis Bacquet, P. Szriftgiser, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Alexandre Beck, Jean-Francois Lampin

Narrow linewidth THz generation using a cascaded Brillouin fibre laser structure and a unitraveling carrier photodiode is proposed. Using two distributed feedback lasers separated by > 1 THz with 1 MHz initial linewidth, the linewidth of the realized THz source is found to be < 100 Hz at 1014…

Synthesis and electrical conductivity of multilayer silicene

Patrick Vogt, Pierre Capiod, Maxime Berthe, Andrea Resta, Paola de Padova, Thomas Brühne, Guy Le Lay, B. Grandidier

The epitaxial growth and the electrical resistance of multilayer silicene on the Ag(111) surface has been investigated. We show that the atomic structure of the first silicene layer differs from the next layers and that the adsorption of Si induces the formation of extended silicene terraces…

Microwave optical switches metal-semiconductor-metal Schottky based on GaAs

Sabah Benzeghda, Farida Hobar, Didier Decoster, Jean-Francois Lampin, A. Benzeghda

Interdigitated metal-semiconductor-metal (MSM) photodetectors have received considerable attention for applications in microwave optical phoswitches. The impulse response of interdigitated metal-semiconductor- metal photoswich fabricated on GaAs non-intentional doped (NID) absorbing layer is…

A one-dimensional optomechanical crystal with a complete phononic band gap

J. Gomis-Bresco, D. Navarro-Urrios, M. Oudich, Said El-Jallal, A. Griol, D. Puerto, E. Chavez, Yan Pennec, Bahram Djafari-Rouhani, F. Alzina, A. Martínez, C.M. Sotomayor Torres

Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Among their physical implementations, optomechanical (OM) crystals built on semiconductor slabs enable the integration and manipulation of…

Thermoelectric infrared microsensors based on a periodically suspended thermopile integrating nanostructured Ge/SiGe quantum dots superlattice

Katir Ziouche, G. Savelli, Zahia Bougrioua, D. Hauser, P. Lejeune, P.M. Michon, Tuami Lasri, Didier Leclercq

This paper presents an original integration of polycrystalline SiGe-based quantum dots superlattices (QDSL) into Thermoelectric (TE) planar infrared microsensors (μSIR) fabricated using a CMOS technology. The nanostructuration in QDSL results into a considerably reduced thermal conductivity by a…

Unconventional thin-film thermoelectric converters : structure, simulation, and comparative study

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Bi2Te3 or Sb2Te3 are the materials most widely used in thermoelectric generators (TEG) operating near room temperature. These materials are, however, environmentally harmful, expensive, and incompatible with complementary metal-oxide semiconductor technology, in contrast to silicon (Si), germanium…
