Through precise fabrication techniques and KOH post-cleaning following Ar-based etching, we achieved effective optical performance across key parameters such as transmission loss, splitting ratios, and Q-factors. These results show the potential of lithium niobate in advanced photonic applications, paving the way for its use in integrated on-chip photonics.
