Grating couplers form a crucial interface between optical fibres and integrated lithium niobate waveguides, addressing the fundamental challenge of mode‐field and refractive‐index mismatch. By ...
“We apply a systematic inverse design approach to discover foundry-compliant, multilayer grating couplers that can efficiently couple a number of independent waves from free space to on-chip ...
