|Title:||Design, simulation and experimentation for the geometric of optofluidic prism||Authors:||Leong, Amanda Si Min.||Keywords:||DRNTU::Engineering::Nanotechnology||Issue Date:||2011||Abstract:||This report investigates the parameters affecting the performance of an optofluidic prism which is realized by two laminar flows in a microfluidic chip. The tunable optofluidic prism can precisely adjust the optical path in an integrated on-chip system and has potential applications for optical detection and biochemical analysis. Aiming to get a large tuning range, long working distance and high stability of the optofluidic prism, several parameters of the chip are of concern in this report: the apex angle of the chamber, the inlet width and the size of the device. In addition, the effects of the flow condition on the prism are also discussed. For instance, the prism shape is changed with the ratio of the flow rates between two flows, and the diffusion is increased with flow rates. The effects of these parameters is simulated by COMSOL and verified by hydrodynamic experiments. The results of the experiments are shown to be very close to the theoretical estimates. Based on the simulation and experimentation, an optimal chip design is built and a suitable flow rate range is proposed to get high performace of the optofluidic prism.||URI:||http://hdl.handle.net/10356/45361||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
