Abstract :
We present for the first time that fluidic and optical behavior of liquid within the micro channels has been modeled, simulated and experimented for the various geometries with constant depth of 160 μm. These channels are all rectangular in cross section made of transparent PDMS (Polydimethylsiloxane) through a molding process from a master of a SU-8 patterned wafer (4 inches in diameter). Each flexible channel varies in two-dimensional (2D) outline including rectilinear, curved and rectangular shapes. An optical camera and a spectrum analyzer were equipped to capture and analyze the dynamic evolutions of optofluidic flows supplied by a liquid injector. The light guide by the total reflection was proved feasible for many liquid solutions.
