3D Printed Microplatform for Fiber-Coupled Optical Microsystems

In this paper, a 3D printed microplatform for realization of fiber-coupling between a light source and an optical microsystems is proposed. The micro-platform is designed in a CAD software and printed using additive manufacturing fusing technology. The performance of the proposed microplatform is tested successfully by coupling an integrated CMOS photodiode with an area of 500 x 500 mu m(2) to a pig tail laser that is attached to a 62.5 mu m/125 mu m multimode fiber optic cable. Experiment results show that the proposed microplatform presents a cost-effective alternative to the silicon-processed microplatforms.
