Microwave modulation of terahertz quantum cascade lasers : a transmission-line approach

Wilfried Maineult, Lu Ding, Pierre Gellie, Pascal Filloux, Carlo Sirtori, Stefano Barbieri, Tahsin Akalin, Jean-Francois Lampin, Isabelle Sagnes, Harvey E. Beere, David Ritchie

We report on microwave impedance measurements of metal-metal ridge-waveguide terahertz quantum cascade lasers. Experimental data, recorded at 4 K in the 100 MHz–55 GHz range, are well reproduced by distributed-parameter transmission-line simulations, showing that the modulation cutoff is limited by…

Graphene growth by molecular beam epitaxy on the carbon-face of SiC

E. Moreau, S. Godey, F.J. Ferrer, D. Vignaud, X. Wallart, J. Avila, M.C. Asensio, F. Bournel, J.J. Gallet

Graphene layers have been grown by molecular beam epitaxy (MBE) on the (0001¯) C-face of SiC and have been characterized by atomic force microscopy, low energy electron diffraction (LEED), and UV photoelectron spectroscopy. Contrary to the graphitization process, the step-terrace structure of SiC…

Microstub resonators based-waveguides for filtering and multiplexing devices

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, A. Noual, L. Dobrzynski

In this chapter, we report numerical simulations, based on a two dimensions Finite Difference Time Domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. This resonator offers a filtering alternative to well-…

Existence and collapse of Fano resonances as a function of pinning field in simple mono-mode magnetic circuits

Housni Al-Wahsh

We consider, in the frame of long-wavelength Heisenberg model, the effect of a pinning field on the spin wave band gaps and transmission spectra of a simple magnonic device. This simple device is composed of an infinite one dimensional (1D) monomode waveguide (the backbone) along which N (N’) side…
