<p>The opto-fluidic device (10) includes three plates which together bound a number of passages including an interaction passage (30) having opposite ends (27,29), an inlet channel (15) which opens into one of such ends (27), and two outlet channels (50a,50b) which open into the other end (29) of the interaction passage (30) at symmetrically arranged outlet regions (51a,51b). Fluid is caused to flow through the inlet channel (15) into the interaction passage (30) to form a jet stream that flows toward the outlet regions (51a,51b). After the flow of the fluid through the inlet channel (15) has been intentionally disturbed by heating a transversely off-set light-absorbing zone of the inlet channel (15) by a light beam with attendant heating of the fluid flowing past such zone and initial transverse deflection of the jet stream, the extent of such deflection is enhanced by supplying additional amounts of the fluid to symmetrically situated lateral locations of the interaction passage (30) so that the jet stream permits more of the fluid to enter the interaction passage (30) from that of the locations from which it deflected away than from the other locations with attendant additional deflection of the jet stream.</p> |
