High-dimensional Supermode Photonics Enabled by Hierarchical Supersymmetric Transformation
Yuan Zhong, Kaile Chen, Qi Lu +8
Modes provide a fundamental degree of freedom for photonic information processing, yet conventional multimode waveguides exhibit non-equidistant effective-index distributions, maki…
Integrated Supermode Photonics Enabled by Supersymmetric Transformation
Kaile Chen, Qi Lu, Yuan Zhong +6
We report a systematic methodology to obtain supermodes with equidistant effective index distribution and to excite arbitrary target supermodes with high precision. By employing a…
Quaternion optical computing chip for parallel high-dimensional data processing
Songyue Liu, Qi Lu, Yuan Zhong +6
Optical computing chips have emerged as a transformative computing technology due to their high computational density, low energy consumption, and compact footprint. While real- an…
Approaching High-efficiency Spatial Light Modulation with Lossy Phase-change Material
Luoyao Chu, Yan Li, Shunyu Yao +3
The prevalent high intrinsic absorption in the crystalline state of phase-change materials (PCMs), typically leads to a decline in modulation efficiency for phase-change metasurfac…
