Following publication of the original article [1], the authors identified an error in Fig. 3b. The correct Fig. 3 is in this correction, and the original article has been corrected.
a Schematic of the device measurement. PC, polarization control; TM-GC, TM polarization sensitive grating coupler; TE-GC, TE polarization sensitive grating coupler; OSA, optical spectrum analyzer. b Top-view SEM picture of fabricated converters. c Measured transmission of TE0 mode (red line) and TM0 mode (blue line); the black line are trend lines by robust locally weight regression method. The green line represents the polarization dependent loss (PDL)
