Fabrication of a 3D mode size converter for efficient edge coupling in photonic integrated circuits
Hyeong-Soon Jang, Hyungjun Heo, Sangin Kim +6
We demonstrate efficient edge couplers by fabricating a 3D mode size converter on a lithium niobate-on-insulator photonic platform. The 3D mode size converter is fabricated using a…
