Definition
Optofluidics refers to the microfluidic area where optics and fluids are coupled together to create optical functions in fluids or, conversely, to actuate fluids at a micrometric scale with optics. Optohydrodynamics more specifically corresponds to the latter case, where light sets fluids in movement either transiently or permanently.
Physical Principles
Electromagnetic waves possess energy and momentum (linear, angular, or orbital) that can be exchanged with or transferred to matter. A force density can result from this interaction whenever photon momentum undergoes a modification in amplitude and/or in direction as illustrated, for instance, in optical levitation, trapping, and tweezing of microparticles [1]. Photons may be reflected and/or transmitted at the interface separating two media of different index of refraction, and momentum conservation results in the so-called optical...
