Plastic optical fiber star coupler

Fabrication and Characterization of N×N Plastic Optical Fiber Star Coupler based on Fused Combining

“…The excess losses of both devices were less than 1.25 dB and 1.73 for 4×4 type and 6×6 type POF star couplers respectively, which is 1.0~1.5 dB smaller than the previously reported POF star couplers. [9,10] We guess that this smaller loss was attributed to the transition regions. Due to the transition regions, there was no structural discontinuity along the longitudinal direction of the coupler.…”

“…In particular, the optical network used in automobiles is evolving from a ring bus network into a star network as the demand for high speed data communication grows. [1] There have been many approaches to the fabrication of POF couplers, such as side-polishing, [2,3] twisting and fusing, [4,5] molding, [6] mixing rods, [7] using hollow taper waveguide, [8] one dimensional layer cavity [9] and polymer rectangular waveguide. [10] High performance as well as simple fabrication for mass production is required for the POF couplers.…”

“…There have been many approaches to the fabrication of POF couplers, such as side-polishing, twisting and fusing , molding , mixing rods , using hollow taper waveguide, one dimensional layer cavity polymer rectangular waveguide, metallic waveguide methods [1][2][3][4]. In this paper, we have examined feasibility of the fused combining technology for general N  N type of POF star couplers and reported performance of the devices.…”

“…Star couplers are widely used for both time-division-and wavelength-divisionbased networks, such as optical buses. One way to fabricate POF star couplers [11] is to use a planar structure, where a one-dimensional flat cavity is sandwiched between input and output linear arrays of POFs. The fusion and the tapering methods [6,7] are other approaches for getting star couplers.…”
