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…
Aluminum nitride waveguide beam splitters for integrated quantum photonic circuits
Hyeong-Soon Jang, Donghwa Lee, Hyungjun Heo +7
We demonstrate integrated photonic circuits for quantum devices using sputtered polycrystalline aluminum nitride (AlN) on insulator. The on-chip AlN waveguide directional couplers,…
Experimental comparison of various quantum key distribution protocols under reference frame rotation and fuctuation
Juhwan Yoon, Tanumoy Pramanik, Byung Kwon Park +4
In free-space quantum key distribution (QKD) between moving parties, e.g., free-space QKD via satellite, the reference frame rotation and fluctuation degrades the performance of QK…
