Article Synopsis
  • The study introduces a high positional freedom (HPF) grating coupler made from a single etch-step subwavelength grating (SWG) on a 220 nm silicon-on-insulator (SOI) substrate, designed specifically for 1550 nm light with TE polarization.
  • This grating coupler achieves a maximum coupling efficiency of -7.49 dB (equivalent to 17.8%) and demonstrates impressive bandwidths of about 14 nm for -1 dB and 29.5 nm for -3 dB.
  • It is notable for achieving the highest -1 dB single mode fiber lateral alignment reported, measuring 21.4 μm by 10.1 μ
