Abstract

Abstract

Biosensors incorporating optofluidic waveguides take advantage of a full suite of integrated optical structures. Compatible with visible wavelengths, these labs-on-chip are constructed primarily from silica films on silicon substrates and include optimized liquid core, buried rib, and multi-mode-interference (MMI) waveguides.

Abstract

Abstract

I will discuss applications of a waveguide-based chip-scale platform for ultrasensitive biomolecule analysis. Examples include amplification-free detection of nucleic acids, multiplex detection of single viruses using MMI waveguides, simultaneous detection of proteins and nucleic acid biomarkers, and integration of nanopores for electro-optical single molecule analysis.

Abstract

Abstract

Combining light and sound, photoacoustic imaging (PAI) is a powerful tool for anatomical, functional, and molecular imaging. We are pioneering in multiple PAI new technologies that have collectively enabled miniaturized, deep, and high-sensitivity biomedical applications in drug screening, early cancer detection, and neuronal activity imaging.

MH4.1 - PHOTONIC RESONATOR HYBRIDS FOR ULTRASENSITIVE LIQUID BIOPSY OF NUCLEIC ACID BIOMARKERS FOR CANCER

Abstract

Abstract

We demonstrate Photonic Resonator Absorption Microscopy in which plasmonic nanoparticles are easily detected through hybrid resonant coupling when attached to a photonic crystal. The approach is used to detect miRNA cancer biomarkers with digital precision and 100 aM detection limits.

Abstract

Abstract

Three-dimensional hydrodynamic focusing promises to enhance detection capabilities of optofluidic sensors, enabling low concentration interrogation with higher confidence, critical for disease diagnosis. Novel 3DHDF designs with optofluidic channel diameters in the range of ten microns are evaluated, predicting detection enhancement of up to 3.54 times.

MH4.3 - FREE SPACE EXCITATION IN OPTOFLUIDIC DEVICES FOR SINGLE PARTICLE DETECTION

Abstract

Abstract

Free space top-down illumination of liquid-core waveguides in an optofluidic chip is implemented by milling slits into a metal layer covering the waveguide channel. Detection of single microbeads with excellent signal-to-noise ratio is demonstrated for different milling depths.

Abstract

Abstract

MIMO complexity can be reduced or avoided completely by proper design of the few mode optical fiber used for mode division multiplexing. Our focus is high index contrast fibers that avoid the formation of scalar modes, to favor vector modes with more limited modal interactions.
