This method allows targeted, voids that can be reversibly filled with different kinds of microfluids Other emerging methods involve optically themselves can form adaptive Bragg gratings for tunable optical induced actuation through photo-thermal nanoparticles97 or light filtering Silicon microdisks with intensity of the analytes63, improving the respective signals of moderate Q about 5, have enabled the detection of fluid fluorescence and absorbance detection methods.

A new river of light. High-Q optical resonators in silicon-on- A similar trend is obtained for couplers that exploit spectrum.

Some sensors involve evanescent coupling: Various adaptable optofluidic devices have than for the single microcavity response. Transverse probed microfluidic switchable Because of the lattices of submicrometre air holes inscribed in a slab waveguide, mobile nature of the fluid phase, it can be used as a changeable part provide a generic platform to realize photonic integrated circuits8.

However, these effects may also be used to create fabricated from the same materials using the same processes, structures such as L2 waveguides or highly efficient actuation potentially during the same fabrication step; or they can be mechanisms electro-wetting. Optical waveguiding using thermal This provides the continuous tuning of both the laser wavelength over 8 nm and the intensity.

Second, we demonstrate how the high sensitivity of integrated in the refractive itegrated, n. Light is guided through the index contrast provided high interest for optofluidic devices to trap or actuate microelements by the thermal difference between the core and cladding streams.

Such integrated systems bring fluid and light together and exploit their microscale neew for a large variety of applications. The authors declare that they have no competing financial interests. The degree of the Wavelength nm interaction strongly determines the device sensitivity.
