Popis: A III-V/Si/Si 3 N 4 structure critical in realizing high-performance lasers can be fabricated using microtransfer printing. This approach poses stringent requirements on the $\text{Si}_{3}\mathrm{N}_{4}-\text{Si}$ couplers. Accordingly, we realized $174\ \mu \mathrm{m}$ long, fabrication-tolerant Si tapers with simulated losses below 0.8 dB up to 750 nm misalignment.
