The paper deals with optical microelectromechanical systems (MEMS), and in particular with optical MEMS based on moving waveguides. After a short overview of this very attractive novel activity, specific technological problems and solutions are discussed. Then the following examples of recent developments based on silica on silicon technology are presented:(More)
Similar to transistors, the size of MEMS components is continuously shrinking, progressing from MicroElectroMechanical Systems to NanoElectroMechanical Systems (NEMS). Indeed, NEMS are emerging as a new field of interest because their submicron dimensions make them converge towards CMOS fabrication processes. They have specific advantages such as fast(More)
A 14-MHz in-plane nanoelectromechanical resonator based on a resonant-suspended-gate (RSG) MOSFET principle and integrated in a front-end process is demonstrated. The devices are in-plane flexural vibration mode beams (L = 10 μm, w = 165 nm, and h = 400 nm) with 120-nm gaps. This letter details the design and process flow fabrication steps. Then, the(More)
Due to the increasing complexity of optical networks, low speed, polarisation and wavelength insensitive fiber compatible optical switches become more and more interesting, especially for network safety and network reconfiguration. We propose an integrated opto-mechanical switch by combining two mass-production technologies: integrated optics on silicon and(More)
We report here the first realization of top-down silicon nanowires (SiNW) transduced by both junction-less field-effect transistor (FET) and the piezoresistive (PZR) effect. The suspended SiNWs are among the smallest top-down SiNWs reported to date, featuring widths down to ~20 nm. This has been achieved thanks to a 200 mm-wafer-scale, VLSI process fully(More)
A new micro-optical vibration sensor has been achieved by combining “integrated optics” and “micromachining” on silicon technologies. The high sensitivity and the wide frequency range have been obtained by using a multimode section in the optical detection circuit. Three prototypes have been installed successfully in an industrial hydroelectric power plant.
The paper reports on in-plane nanometer scale resonators fabricated on 8 inch industrial tools, with a process based on the advanced CMOS Front End Silicon On Nothing Technology. The aim is to propose totally integrated time reference functions realized by small size NEMS resonators. The measurement set-up, simulation and experimental results in the range(More)
This work reports on top-down nanoelectromechanical resonators, which are among the smallest resonators listed in the literature. To overcome the fact that their electromechanical transduction is intrinsically very challenging due to their very high frequency (100 MHz) and ultimate size (each resonator is a 1.2 μm long, 100 nm wide, 20 nm thick silicon beam(More)
