| Abstract: | The previous PLC E-31 and E-13 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(31)-E-13 modes, as well as E-31-LP0(2) and E-13- LP21b modes, respectively. The E-31-E-13 mode converter can be reduced from the previous three-stage linear taper of 12000 μm to approximately 4000 μm in length. Similarly, the E-31-LP02, E-13-LP21b mode converter can be reduced from the previous two-stage linear taper of over 6000 μm to approximately 4000 μm in length. |
