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…
Localized crystallization of Ce:YIG thin films on Si using CO2 laser annealing for integrated nonreciprocal photonic device applications
Xinran Ji, Junxian Wang, Tianchi Zhang +6
Laser annealing (LA) technique has emerged as an effective method for localized crystallization of magneto-optical (MO) garnet thin films on semiconductor substrates. However, no s…
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…
YbNiMg: Superheavy fermion with enhanced Wilson ratio and magnetocaloric effect
Xiaoci Zhang, Te Zhang, Zhaotong Zhuang +6
A comprehensive study of the low-temperature properties of YbNiMg has revealed evidence of a superheavy-fermion state, characterized by a large electronic specific-heat coeffic…
