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…
Ultrafast Reconfigurable Topological Photonic Processing Accelerator
Wenfeng Zhou, Xin Wang, Xun Zhang +12
The rise of artificial intelligence has triggered exponential growth in data volume, demanding rapid and efficient processing. High-speed, energy-efficient, and parallel-scalable c…
Arbitrary control of the flow of light using pseudomagnetic fields in photonic crystals at telecommunication wavelengths
Pan Hu, Lu Sun, Ce Chen +5
In photonics, the idea of controlling light in a similar way that magnetic fields control electrons has always been attractive. It can be realized by synthesizing pseudomagnetic fi…
