Paper Abstract

A chip of fiber optical trap paves the way to realize the miniaturization and portability of devices based on dual beam optical trap, without loss of stability. We have designed two types of chip of fiber optical trap according to our theoretical simulation. The first one integrates dual beam optical trap with microfluidic chip, called a chip of semi-sealing fiber optical trap. It is generally used in chemical, biological, medical and other high-throughput experiments. The second one is a chip of full-sealing fiber optical trap. It is used to measure precisely the coefficient of viscosity or the Brownian movement of micro-object’s in liquid. This paper focuses on the chip of fiber optical trap. We present two types of chips of fiber optical trap and detail their designs, fabrication and validation. The chip of semi-sealing fiber optical trap is integrated with optical fiber and microfluidic chip made of polydimethylsiloxane (PDMS). We have achieved the micro-sized alignment of optical paths and the trapping of micro-sized particles in the chip of semi-sealing fiber optical trap. In addition, it is easy to fabrication and clean. The chip of full-sealing fiber optical trap was based on a cubic micro-cavity made by a rectangular capillary tube and sealed by PDMS. We have achieved micro-sized alignment accuracy, high trapping efficiency and better trapping stability in the chip of full-sealing fiber optical trap as well.
