A miniature frequency-stabilized VCSEL system emitting at 795nm based on LTCC modules

Nico de Rooij, Thomas Maeder, Yves Pétremand, Fabrizio Vecchio

We present a compact frequency-stabilized laser system locked to the Rubidium absorption line of a micro-fabricated reference cell. A printed circuit board (PCB) is used to carry all the components and part of the electronics, and low-temperature co-fired ...

A portable lab-on-a-chip instrument based on MCE with dual topbottom capacitive coupled contactless conductivity detector in replaceable cell cartridge

Nico de Rooij

A new design for a compact portable lab-on-a-chip instrument based on MCE and dual capacitively coupled contactless conductivity detection (dC4D) is described. The instrument is battery powered with total dimension of 14 x 25 x 8 cm3 (w x l x h), and weigh ...

Piezoresistive Membrane-Type Surface Stress Sensor Arranged In Arrays For Cancer Diagnosis Through Breath Analysis

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Vettiger, Frédéric Loizeau, Christoph Gerber

We present the fabrication, characterization and successful medical application of a membrane-type surface stress sensor (MSS), arranged in arrays for molecular detection in gaseous phase. Made out of SOI substrate, a round membrane with a diameter of 5 0 ...

The two-dimensional array of 2048 tilting micromirrors for astronomical spectroscopy

Nico de Rooij, Michael David Canonica, Wilfried Noell

In multi-object spectrometers, field selectors, which are located in the focal plane of the telescopes, are required for the selection of astronomical objects, such as stars or faint galaxies. We present a two-dimensional micromirror array as a field selec ...

Batch fabrication of gold-gold nanogaps by E-beam lithography and electrochemical deposition

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Yexian Wu

We report on the successful development of a well-controlled two-step batch nano-fabrication process to achieve nanometer-size gaps at the wafer scale. The technique is based on an optimized electron-beam lithography process, which enables the fabrication ...

High-temperature compatible 3D-integration processes for a vacuum-sealed CNT-based NEMS

Nico de Rooij, Danick Briand, Terunobu Akiyama, Rokhaya Gueye

A System-in-Package (SiP) concept for the 3D-integration of a Single Wall Carbon Nanotube (SWCNT) resonator with its CMOS driving electronics is presented. The key element of this advanced SiP is the monolithic 3D-integration of the MEMS with the CMOS elec ...

In-Plane Fabricated Insulated Gold-Tip Probe For Electrochemical And Molecular Experiments

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Van der Wal, Yexian Wu

In this contribution we present a scanning probe with a gold-tip completely encapsulated with insulator all the way to the apex. The probe fabrication is unique owing to an in-plane arrangement in which the width of the cantilever is defined by deep reacti ...
