“…The increase in the field strength leads to an enhancement of the nonlinear response of the medium, a property that has been used for surface-enhanced Raman scattering. Thermal nonlinearities introduced by metal nanoparticles in a solvent were recently used to demonstrate holographic recording in a fluid 65 . …”

We describe devices in which optics and fluidics are used synergistically to synthesize novel functionalities. Fluidic replacement or modification leads to reconfigurable optical systems, whereas the implementation of optics through the microfluidic toolkit gives highly compact and integrated devices. We categorize optofluidics according to three broad categories of interactions: fluid-solid interfaces, purely fluidic interfaces and colloidal suspensions. We describe examples of optofluidic devices in each category.Optofluidics refers to a class of optical systems that are synthesized with fluids. Fluids have unique properties that cannot be found in solid equivalents, and these properties can be used to design novel devices. Examples of such properties include: the ability to change the optical property of the fluid medium within a device by simply replacing one fluid with another; the optically smooth interface between two immiscible fluids; and the ability of flowing streams of miscible fluids to create gradients in optical properties by diffusion. Most optical systems are currently made with solid materials such as glasses, metals and semiconductors, but there are cases in which it has been advantageous to use fluids. The oil-immersion microscope 1 , liquid mirrors for telescopes 2 , liquid-crystal displays 3 and electrowetting lenses 4 are good examples. Here we describe the various methods used to implement optofluidic devices with recently developed microfluidic technologies that allow accurate control of liquids on small spatial scales. Integration and reconfigurability are two major advantages associated with optofluidics. Whereas microfluidics has made it possible to integrate multiple fluidic tasks on a chip, most optical components, such as the light source, sensors, lenses and waveguides, remained off the chip. Optofluidic integration combines optics and microfluidics on the same chip by building the optics out of the same fluidic toolkit. The second advantage of optofluidics lies in the ease with which one can change the optical properties of the devices by manipulating fluids.Microfluidics is a burgeoning field with important applications in areas such as biotechnology, chemical synthesis and analytical chemistry. Many of these applications of microfluidics are discussed elsewhere in this issue, and for the purposes of this Review we emphasize only a few salient points. First, there is now an extensive body of literature on how the physical properties of fluids that are available only on small spatial scales can be exploited for device functionality [5][6][7] . Many of these effects can also be used to control optical properties. Second, technological advances in device fabrication have made it possible to build miniaturized devices with complex networks of channels, valves, pumps and other methods of fluidic encapsulation and manipulation 8 . This creates a powerful set of tools for fluidic control, and because the feature sizes in these systems are shrinking over time, they will inevitably appro...

“…The thickness of the fringes (as well as the polymer) is also significant for the propagation distance of the evanescent waves to reach the surface (Cho, 2010;Cowan, 1972;OzakI and Kawata, 2011;Monis, 2010) and contributes to wavelength modification. Thus, the concentration of the nanoparticles in the fringes in the polymer affects the diffraction efficiency of the grating (Adleman et al, 2006) via refractive index modulation (Naydenova et al, 2005). The developed metal grains in the opaque fringes ultimately absorb most of the light (coherent laser or white lamp) that is interacting with them and they selectively scatter the rest in the form of standing waves of different potential energy (Bendana et al, 2010;Gaponenko, 2010;Saxby, 2004) thus the reflection efficiency of such fringes is similarly dependent on the characteristics of the metal particles and the fringe periodicity (as well as refractive index) which then influences the interference of the SPR on the holographic replay.…”
