Polarization-insensitive 1D grating coupler based on a zero-birefringence subwavelength corelet waveguide

Grating coupler devices provide efficient, foundry-compatible vertical fiber-to-chip coupling solutions in integrated photonic platforms. However, standard grating coupler designs are highly polarization sensitive, which hinders their adoption. We present a new, to the best of our knowledge, type of...
