Science and Engineer Importance to Singapore

Singapore has boosted its water supply through water-recycling and also increased its land area by reclaiming land, all feats accomplished by engineers. And engineering will continue to be important for Singapore's future, as the country works towards becoming a smart nation and overcoming its lack of resources

Design and Analysis of Microfluidic Optical Fiber Device for Refractive Index Sensing

Jun Long Lim, et al.


IEEE Photonics Technology Letters (PTL)


Abstract—In this letter, the microfluidic optical fiber devices composed of microchannel are modeled and thoroughly analyzed. The microchannel intersecting the fiber core allows direct infusion of surrounding substances for detection. The simulation results suggest that the dimension of the microchannel can significantly affect the detection sensitivity of the device. In addition, the off-center position of the microchannel also plays an important role in shaping the device performance. The optimized microfluidic device can be used for sensitive refractive index sensing and biosensing applications.
