Refractive Index Gas Sensing in a Hollow Photonic Crystal Cavity

Romuald Houdré, Hua Zhang, Nicolas Le Thomas, Jana Jágerská, Zhaolu Diao

We investigate hollow photonic crystal structures consisting in air-slot photonic crystal nanocavities. The high quality factor similar to 2.6x10(4) of such cavities along with a strong overlap between the resonant mode and the hollow core region allows fo ...

Inhibited emission of electromagnetic modes confined in subwavelength cavities

Romuald Houdré, Nicolas Le Thomas

We experimentally demonstrate the active inhibition of subwavelength confined cavity modes emission and quality factor enhancement by controlling the cavity optical surrounding. The intrinsic radiation angular spectrum of modes confined in planar photonics ...

Switchable bandpass filter for WiFi-UMTS reception standards

Julien Perruisseau-Carrier

A reconfigurable bandpass filter able to switch between WiFi and UMTS reception standards is presented. The topology allows achievement of two accurate centre frequencies, each associated with a precisely defined bandwidth, using six pin diodes. The design ...

Resonant-Body Fin-FETs with sub-nW power consumption

Mihai Adrian Ionescu, Andrea Lovera, Dimitrios Tsamados, Daniel Grogg, Sebastian Thimotee Bartsch

This paper presents, for the first time, experimental evidence on resonant-body Fin-FETs (RB-FinFET) with two independent lateral gates, operated from weak to strong inversion, which enables unique trade-off between power consumption and gain. Resonance fr ...
