Paper Abstract

Lab-on-a-chip and optofluidic micro-systems often rely on bulky off-chip optical components such as lenses and spectrometers for detection. There is a growing demand for compact microspectrometers that can be integrated on-chip, to increase portability and potentially reduce the cost and complexity of these systems. We have previously reported chip-scale microspectrometers based on tapered air-core Bragg waveguides with omnidirectional Bragg claddings. Here, we describe the integration of these air-core waveguide spectrometers with microfluidics, including results for a prototype sensing system based on spectrally-resolved fluorescence detection.
