Cocaine detection by a mid-infrared waveguide integrated with a microfluidic chip
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 m, which is emitted from a quantum cascade laser. This device is...

| description | 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 m, which is emitted from a quantum cascade laser. This device is ideal for (bio-)chemical sensing applications.
We present a mid-infrared waveguide integrated with a microfluidic chip for sensing in a liquid environment. |
