Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses. However, the efficiency of the optical-to-THz conversion remains limited. Although…

Victor Fiorese, Joao Carlos Azevedo Goncalves, Simon Bouvot, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière, Emmanuel Dubois

This article introduces the first BiCMOS SiGe technology based packaged noise source (NS) operating in G-band (140-220 GHz). An amplified PN junction diode has been packaged and biased in avalanche mode to generate Excess Noise Ratios (ENRav) of approximately 25 dB between 140 and 170 GHz at…

Tilt-related alignment issues in miniature micromechanical on-wafer electrical probes composed of multiple flexible microcantilevers

Steve Arscott

Abstract Some new issues concerning the contacting and positioning of small electrical microelectromechanical systems (MEMS) probes based on multiple, flexible microcantilevers are presented here. A tilt error, associated with the lateral probe roll, means that contact touchdown occurs sequentially…

Optical Tamm states in 2D nanostructured magnetophotonic structures

Baptiste Mathmann, Oumaima Haidar, Abdelkrim Talbi, Nicolas Tiercelin, Abdallah Mir, El Houssaine El Boudouti, Bahram Djafari-Rouhani, Gaëtan Lévêque, Abdellatif Akjouj, Yannick Dusch

We numerically explore optical Tamm states (OTS) supported by a photonic structure composed of a nanostructured metallic layer on top of a distributed Bragg reflector (DBR). Several polarizations, incidences and patterning are assessed to map OTS and their properties. We then gain magnetic control…
