Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current…

9 - Electromagnetic Induced Transparency, Induced Absorption, and Fano Resonances in Photonic Circuits

El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani, Abdelkrim Talbi, L. Dobrzynski

In this chapter, a simple photonic device consisting of two dangling side resonators grafted at two sites (U-shape) or at the same site (cross-shape) along a waveguide is designed in order to obtain sharp resonant states inside the transmission gaps without introducing any defects in the structure…

19 - Optical Waves in Finite Layered Photonic Crystals

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani

We investigated the propagation of electromagnetic waves in a finite photonic crystal bounded by a substrate and vacuum, and separated from them by a buffer layer and a cap layer. In this realistic geometry, we show the existence of different kinds of localized and resonant modes whose behaviors…

13 - Fibonacci Loop Structures: Bandgaps, Power Law, Scaling Law, Confined and Surface Modes

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

We study theoretically and experimentally the existence and behavior of scaling law, power law, as well as confined and surface modes in one-dimensional (1D) quasiperiodic photonic bandgap structures. These structures are made of segments and loops arranged according to a Fibonacci sequence. We…
