TLDR
Multimode polymer waveguides and fiber-to-waveguide couplers have been integrated with microfluidic channels by use of a single-mask-step procedure, which ensured self-alignment between the optics and the fluidics and allowed a fabrication and packaging time of only one day.Abstract:
Multimode polymer waveguides and fiber-to-waveguide couplers have been integrated with microfluidic channels by use of a single-mask-step procedure, which ensured self-alignment between the optics and the fluidics and allowed a fabrication and packaging time of only one day Three fabrication procedures for obtaining hermetically sealed channels were investigated, and the spectrally resolved propagation loss (400–900 nm) of the integrated waveguides was determined for all three procedures Two chemical absorbance cells with optical path lengths of 100 and 1000 μm were furthermore fabricated and characterized in terms of coupling loss, sensitivity, and limit of detection for measurements of the dye bromothymol blueread more

Fabrication and measurement of optical waveguide sensor based on localized surface plasmon resonance
TL;DR: In this paper, a localized surface plasmon resonance (LSPR) sensor system based on polymer material is proposed, which consists of the incident medium with low-loss polymer waveguide and the chemically immobilized plasmoric nanoparticles for on-chip LSPR sensing.

Fluorescence-detected assays on microfluidic chips
TL;DR: In this article, a photonic system with two or more rectangular waveguide structures (62, 66, 63) arranged on the chip that are able to guide excitation light in the near IR, visible, or near UV range is described.

A microfluidic-photonic-integrated device with enhanced excitation power density
TL;DR: In this article, the power density of optical excitation in microfluidic-photonic-integrated flow cytometers is typically provided from an integrated waveguide and the beam is therefore divergent within the microchannel due to the NA of the waveguide.

P. de la Fuente,J.A. Etxeberria,Javier Berganzo,M.T. Arroyo,Enrique Castaño,F.J. Gracia,J. M. Ruano-López +6 more
TL;DR: Blanco et al. as discussed by the authors described the monolithic integration of several optical structures that are needed for optical absorption or scattering measurements, including buried waveguides to confine light, a y-branch splitter to couple light to both photodiodes, a connector for input fibre coupling and a microfluidic circuit with an analytical chamber to allow propagation of light through the substance under analysis.

Microfluidic chips for clinical and forensic analysis
TL;DR: Few cases of microchip analysis of physiological samples or other “real‐world” matrices were found, but many of the examples presented have potential application for these samples, especially with ongoing parallel developments involving integration of sample pretreatment onto chips and the use of fluid propulsion mechanisms other than electrokinetic pumping.
