title = "1× N optical fiber coupler based on a polyhedral gradient index lens",
abstract = "A method for building a 1×N fiber coupler based on a single polyhedral gradient-index lens (p-GRIN) is proposed. One end of the p-GRIN has polyhedral convex cone shape with N surfaces and is used as the light input port, while the other end is flat and used as the output port. When light from a single mode optical fiber illuminates the input end of the p- GRIN, N spatially separated light beams are generated at the output end and coupled respectively into N different output fibers. Results obtained from ray-tracing agree well with simulation results from the ZEMAX software. The output beam positions and light coupling efficiency to optical fibers could be optimized by adjusting the input cone angle and the distance between input fiber end and cone tip. This method may be adapted for any type of optical fibers and provide a practical solution for light coupling between single- and multi-core fibers.",
