Wafer-scale monolithic integration of Ce:YIG films and magneto-optical isolators on silicon
Tianchi Zhang, Yucong Yang, Weihao Yang +9
Silicon integrated cerium doped yttrium iron garnet (Ce:YIG) thin films are promising candidates for integrated nonreciprocal photonic devices, cryogenic photonic modulators and op…
Nonreciprocal optical circuit switching
Zhifeng Tu, Yucong Yang, Yiran Wei +11
Directly switching optical signals outperforms conventional optoelectronic hardware in terms of cost, latency, and energy efficiency, and is expected to address the growing demand…
Unlock giant nonreciprocity via multi-valued behavior of non-Hermitian zero-index materials
Yang Li, Yueyang Liu, Yucong Yang +13
Although Einstein's field equations are time-independent, the multivalued feature of the horizon of a blackhole naturally enables the one-way transmission, leading to the strong ar…
Nonreciprocal Optical Routing in Multi-port Magneto-Optical Devices on Silicon
Xiaoyi Song, Wei Yan, Di Wu +7
Nonreciprocal optical devices are key components in photonic integrated circuits for light reflection blocking and routing. Most reported silicon integrated nonreciprocal optical d…
Topology-enabled highly efficient beam combination
Yuhao Jing, Yucong Yang, Wei Yan +7
Beam combination with high efficiency is desirable to overcome the power limit of single electromagnetic sources, enabling long-distance optical communication and high-power laser.…
