Abstract

We propose and demonstrate an ultra-broadband power splitter with arbitrary splitting ratio based on subwavelength gratings (SWGs) multimode interference (MMI) coupler. SWGs are introduced to increase the optical bandwidth of the devices. Asymmetrical MMI regions are used to realize the arbitrary splitting ratio. We have demonstrated the realization of the low loss power splitters with the splitting ratio of 4:6 and 2:8. The measured results for the fabricated devices show that, for both 4:6 and 2:8 devices, loss less than 1.5 dB and splitting ratio variation less than 10% are achieved within a broad optical bandwidth from

基于SWG MMI耦合器的任意分割比超宽带功率分配器

我们提出并演示了一种基于亚波长光栅（SWGs）多模干涉（MMI）耦合器的任意分裂比的超宽带功率分配器。为了增加设备的光带宽，引入了swg。采用非对称MMI区域实现任意分割比。我们演示了分频比为4:6和2:8的低损耗功率分频器的实现。测量结果表明，对于4:6和2:8的器件，在$1.26~ $1.6~ $ μ $ m的宽光带宽范围内，损耗小于1.5 dB，分裂比变化小于10%。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
