Active beam steering enabled by photonic crystal surface emitting laser
Mingjin Wang, Zihao Chen, Yuanbo Xu +4
Emitting light towards on-demand directions is important for various optoelectronic applications, such as optical communication, displaying, and ranging. However, almost all existi…
Low-threshold nanolasers based on miniaturized bound states in the continuum
Yuhao Ren, Peishen Li, Zhuojun Liu +4
The pursuit of compact lasers with low-thresholds has imposed strict requirements on tight light confinements with minimized radiation losses. Bound states in the continuum (BICs)…
Topological unidirectional guided resonances emerged from interband coupling
Xuefan Yin, Takuya Inoue, Chao Peng +1
Unidirectional guided resonances (UGRs) are optical modes in photonic crystal (PhC) slabs that radiate towards one side without the need for mirrors on the other, represented from…
Roadmap on Topological Photonics
Hannah Price, Yidong Chong, Alexander Khanikaev +20
Topological photonics seeks to control the behaviour of the light through the design of protected topological modes in photonic structures. While this approach originated from stud…
