Arrayed Polymer Spot Size Expander applicable to Silicon Photonics Chip for Coupling to Single Mode Fibers

Realization of high coupling efficiency and wide positional tolerance between multi channels of Silicon photonics chip and arrayed single-mode fibers is a challenging issue. To overcome this problem, we proposed integration of arrayed polymer spot size expander which is fabricated by the self-written waveguide technology using UV-curable resin.
