Amorphous silicon microcavities for optofluidic sensing applications

Timo Lipka, Lennart Moldenhauer, Hoc Khiem Trieu

Hamburg University of Technology, Germany

We present integrated optical refractometers and label-free biosensors based on low-loss deposited silicon. Microring, racetrack, and microdisk resonators were employed for volumetric refractive index sensing (IPA, NaCl) and biomolecule immobilization (BSA). The sensors were embedded in PDMS or silicon-glass microfluidic channels and were studied for their sensitivities and detection limits by using conventional wavelength scanning and an on-chip microheater based wavelength-to-power transducer method.

15:00 - 15:30

Reconfigurable optofluidic platform using lightvalves

Holger Schmidt

UC Santa Cruz, United States of America

I will discuss a new optofluidic platform that is based on PDMS waveguides. It enables seamless integration with pneumatically actuatable microvalves. On one hand, this allows for full analysis of biological samples integrating both sample processing and optical detection on a single chip. On the other hand, the microvalves themselves can be designed to act as optical waveguides which allows for design of mechanically reconfigurable photonic devices. Examples for applications of such lightvalves as movable particle traps and high-performance optical and fluidic switches will be discussed.
