Non-volatile integrated photonics on lithium tantalate-on-insulator
Yuhang Li, Miao Deng, Xun Zhang +11
Scalable reconfigurable photonic integrated circuits require low-loss, high-speed optical control without continuous holding power. Yet widely used thermo-optic tuning and continuo…
Leveraging Raman response in X-cut thin-film lithium tantalate for ultrabroadband combs and polychromatic visible light
Xin Wang, Mingkun Xiao, Min Sun +9
X-cut thin-film lithium tantalate (TFLT) offers a unique combination of third nonlinearity, electro-optic effects, and a high optical damage threshold. However, its strong Raman re…
High-power-handling ultra-compact acousto-optic modulators using one-dimensional topological interface states on thin-film lithium tantalate
Yuqi Chen, Wenfeng Zhou, Min Sun +6
Recent advances in integrated photonics have enabled on-chip signal modulation and processing through localized photon-phonon interactions. For acousto-optic devices, compact footp…
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…
