Globally Optimized Ultra-Compact Silicon Edge Coupler with Subwavelength Grating for Sub-1 dB Coupling Loss
This work introduces an ultra-compact edge coupler, which optimized using a global optimization algorithm. The proposed EC achieves a low coupling loss of 0.76 dB at 1550 nm, with a total length of less than <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$51 \mu \mathrm{m}$</tex>.
