On-chip Optofluidic Ring Resonator Sensor for Micro-scale Gas Chromatography

The design, fabrication and preliminary performance assessment of a new vapor sensor comprising a microfabricated optofluidic ring resonator (μOFRR) and its application to microscale gas chromatographic (μGC) detection of volatile organic compounds (VOC) are presented. The μOFRR combines vapor sensing and fluidic transport functions in a micro-fabricated whispering gallery mode (WGM) resonator....

A microfabricated optofluidic ring resonator for sensitive, high-speed detection of volatile organic compounds.

Advances in microanalytical systems for multi-vapor determinations to date have been impeded by limitations associated with the microsensor technologies employed. Here we introduce a microfabricated optofluidic ring resonator (μOFRR) sensor that addresses many of these limitations. The μOFRR combines vapor sensing and fluidic transport functions in a monolithic microstructure comprising a hollo...

Monolithic optofluidic ring resonator lasers created by femtosecond laser nanofabrication.

We designed, fabricated, and characterized a monolithically integrated optofluidic ring resonator laser that is mechanically, thermally, and chemically robust. The entire device, including the ring resonator channel and sample delivery microfluidics, was created in a block of fused-silica glass using a 3-dimensional femtosecond laser writing process. The gain medium, composed of Rhodamine 6G (R...

Optofluidic ring resonator switch for optical particle transport.

In this work, we demonstrate an optofluidic switch using a microring resonator architecture to direct particles trapped in the evanescent field of a solid-core waveguide. When excited at the resonant wavelength, light inserted into the bus waveguide becomes amplified within the ring structure. The resulting high optical intensities in the evanescent field of the ring generate a gradient force t...
