Quantum frequency comb with pump-selectable bin pairing and extraction-aware loading in a lithium niobate microresonator
Mohamad Reza Nurrahman, Hyeon Hwang, Nuri Han +6
Integrated quantum photonics requires bright, high-fidelity photon-pair sources capable of spectral multiplexing, correlation control, and circuit-compatible extraction. Cavity-enh…
Integrated bright source of polarization-entangled photons using lithium niobate photonic chips
Changhyun Kim, Hansol Kim, Minho Choi +10
Quantum photonics has rapidly advanced as a key area for developing quantum technologies by harnessing photons' inherent quantum characteristics, particularly entanglement. Generat…
High-Q photonic crystal Fabry-Perot micro-resonator in thin-film lithium niobate
Hyeon Hwang, Seokjoo Go, Guhwan Kim +5
Thin-film lithium niobate (TFLN) has emerged as a powerful platform for integrated nonlinear and quantum photonics, owing to its strong optical nonlinearities, wide transparency wi…
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…
