In-line microfluidic refractometer based on C-shaped fiber assisted photonic crystal fiber Sagnac interferometer.
We propose and demonstrate a highly sensitive in-line photonic crystal fiber (PCF) microfluidic refractometer. Ultrathin C-shaped fibers are spliced in-between the PCF and standard single-mode fibers. The C-shaped fibers provide openings for liquid to flow in and out of the PCF. Based on a Sagnac interferometer, the refractive index (RI) response of the device is investigated theoretically and ...
متن کاملThree-dimensional Mach-Zehnder interferometer in a microfluidic chip for spatially-resolved label-free detection.
Ultrafast laser writing of waveguides in glasses is a very flexible and simple method for direct on-chip integration of photonic devices. In this work we present a monolithic optofluidic device in fused silica providing label-free and spatially-resolved sensing in a microfluidic channel. A Mach-Zehnder interferometer is inscribed with the sensing arm orthogonally crossing the microfluidic chann...
متن کاملOptofluidic membrane interferometer: An imaging method for measuring microfluidic pressure and flow rate simultaneously on a chip.
We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxane (PDMS) on a glass substrate by multilayer soft lithography. The OMI consists of a flexible air-gap optical cavity which upon illumination ...
متن کاملMicrofluidic refractive index sensor based on an all-silica in-line Fabry-Perot interferometer fabricated with microstructured fibers.
We report a microfluidic fiber-optic refractive index (RI) sensor based on an in-line Fabry-Perot (FP) interferometer, which is formed by a silica tube sandwiched by two microstructured fibers (MFs). The sensor reported here can be fabricated at low cost, possess a robust structure, and has microfluidic capability. The micro-sized holes in the MFs naturally function as microfluidic channels thr...
متن کاملMicrofluidic Systems Integrated Microfluidic Systems**
Microfluidic systems use networks of channels thinner than a human hair to manipulate nanoliter volumes of reagents. The goal of microfluidics is challenging: to integrate, on a chip smaller than a credit card, all operations normally performed in a chemical or medical laboratory. Synthesis, purification, analysis, and diagnostics would be performed by such a “lab on a chip” rapidly, economical...
