چکیده

A germanium (Ge) strip waveguide on a silicon (Si) substrate is integrated with a microfluidic chip to detect cocaine in tetrachloroethylene (PCE) solutions. In the evanescent field of the waveguide, cocaine absorbs the light near 5.8 μm, which is emitted from a quantum cascade laser. This device is ideal for (bio-)chemical sensing applications.

Droplet-based Liquid-liquid Extraction and On-chip Ir-waveguide-spectroscopy Detection of Cocaine in Human Saliva

We present a portable microsystem to quantitatively detect cocaine in human saliva. The chip combines a simple microfluidic method for multiphase liquid-liquid extraction to transfer cocaine from IR-light absorbing saliva to an IRtransparent solvent with the on-chip cocaine detection by IR-waveguide-spectroscopy (QC-laser, waveguide, detector). With our droplet-based extraction method we achiev...

High-brightness lasers on silicon by beam combining

High-brightness lasers are widely used in fields such as spectroscopy, infrared countermeasures, free-space communication, and industrial manufacturing. Integration of a broad-band, multi-spectral laser is made possible by heterogeneously integrating multiple gain materials on one silicon (Si) substrate chip. A single multi-spectral output with high beam quality can be achieved by wavelength be...

Plasmonic waveguide based mid - infrared lab - on - a - chip

Dielectric-loaded plasmonic waveguides are perfectly suitable for on-chip sensing of fluids. They allow long propagation length and large mode overlaps above 96% with a the analyte. Dielectric-loading is a alternative approach to increase the confinement of mid-infrared surface plasmons without the need for sub-wavelength patterning. Direct excitation and detection is realized using chip integr...
