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.
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.

- 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
