Design Considerations For Connectors Of Integrated Optical Strip Waveguides To Single Mode Fiber Arrays
OPTOELECTRONIC INTEGRATED CIRCUITS(1997)
摘要
This paper describes a new design consideration for connectors of integrated optical strip wave-guides to single-mode fiber arrays in silicon V-grooves and some formulas for determining position of fibers and dimensions of silicon V-grooves are derived. The relationship between the coupling efficiency and geometrical parameters of fibers and waveguides in this way also are discussed. We can realize permanent connecting between fibers and waveguides, and simplify the coupling processes of the fibers and the waveguides and increase the coupling efficiency of SM fibers to waveguides. As an example, the coupling efficiency of SM fiber (D = 10 mu m) to SM waveguide (10 mu m X 5 mu m) is up to 55%. The coupling efficiency of SM waveguide to SM fiber is up to 86%.
