Abstract

The previous PLC E31 and E13 mode converters employ linear tapered structures to fulfill the adiabatic coupling condition and achieve a high mode conversion efficiency, which requires long taper lengths. In this paper, we propose two types of PLC tapered structures that can be applied in different scenarios using fast quasiadiabatic dynamics. These structures enable mode conversions of E31-E13 modes, as well as E31-LP02 and E13-LP21b modes, respectively. The E31-E13 mode converter can be reduced from the previous three-stage linear taper of 12000 μm to approximately 4000 μm in length. Similarly, the E31-LP02, E13-LP21b mode converter can be reduced from the previous two-stage linear taper of over 6000 μm to approximately 4000 μm in length.

PLC设计E31-E13以及采用快速准绝热动力学的E-LP锥形模式转换器

以往的PLC E31和E13模式转换器采用线性锥度结构来满足绝热耦合条件并实现高模式转换效率，这需要较长的锥度长度。在本文中，我们提出了两种类型的PLC锥形结构，它们可以应用于不同的场景，使用快速准绝热动力学。这些结构可以实现E31-E13模式、E31-LP02模式和E13-LP21b模式的模式转换。E31-E13模式转换器的长度可以从之前的12000 μm的三级线性锥度减小到约4000 μm。同样，E31-LP02、E13-LP21b模式转换器的长度也可以从之前超过6000 μm的两级线性锥度减小到大约4000 μm。

期刊介绍： An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include: - Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.) - Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.) - Electromagnetic theory - Microwave and millimeter-wave devices, circuits, and modules - THz devices, circuits and modules - Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials) - Integrated circuits (memory, logic, analog, RF, sensor) - Power devices and circuits - Micro- or nano-electromechanical systems - Circuits and modules for storage - Superconducting electronics - Energy harvesting devices, circuits and modules - Circuits and modules for electronic displays - Circuits and modules for electronic instrumentation - Devices, circuits and modules for IoT and biomedical applications
