Aiming efficient multiple simultaneous detection, two different designs of $1\times \text{N}$ power splitters for single source feeding of an N-array biosensors operating at 1550 nm are here proposed and thoroughly compared and discussed. Taking into account the need for micro guiding structures, simpler and cheaper manufacturing processes, SU-8 polymer is adopted as the core material. Our first proposal is based on a cascade arranged directional couplers (DC) with a footprint of $4.2\times 0.42$ mm², uniform power division and losses of $0.54$ dB. The second proposal is based on a multimode interference device (MMI) exhibiting a compact footprint of $1.25\times 0.23$ mm², highly uniform power division and significant low losses of $0.16$ dB.

为了实现有效的多重同时检测，两种不同的设计 $\mathrm{1个}\times \text{ñ}$本文提出并彻底比较和讨论了用于在1550 nm下运行的N阵列生物传感器的单源馈电的功率分配器。考虑到对微引导结构的需求，更简单和更便宜的制造工艺，采用SU-8聚合物作为核心材料。我们的第一个建议是基于级联排列的定向耦合器（DC），其占位面积为$4.2\times 0.42$mm ²，均匀的功率分配和损耗$0.54$D b。第二个建议是基于多模干扰设备（MMI），该设备的占位面积小，$1.25\times 0.23$mm ²，高度均匀的功率分配，损耗低$0.16$ D b。
