Design and fabrication of 1x32 polymer optical power splitter based on EOPCB

基于光束传输方法,设计了一种紧凑的1x32聚合物光功分器。工作中心波长为1550 nm,可应用于光电电路板(EOPCB)。光功分器的长度为20000μm。每个输出端口之间的间距为127μm。光功分器芯层的横截面为10μm x10μm。选用二氧化硅作为包层材料。采用飞秒激光结合湿法刻蚀制备。测试结果表明,光功分器输出端的插入损耗<27dB,均匀性1.2 dB。可以满足EOPCB的光互连。

Based on the beam propagation method,a compact 1x32 polymer optical power splitter is designed.The working center wavelength is 1550 nm,which can be used in photoelectric printed circuit board (EOPCB).The length of the spectrometer is 20,000μm.The spacing between each output port is 127μm.The cross section of the core layer of the optical power splitter is 10μm x10μm.Silicone glass was selected as cladding material.They were prepared by femtosecond laser combined with wet etching.The test results show that the insertion loss of the output of the optical power splitter is less than 27dB and the uniformity is 1.2dB.It can satisfy the optical interconnection of EOPCB.
