Low-loss and broadband non-volatile phase-change directional coupler switches
Peipeng Xu, Jiajiu Zheng, Jonathan Doylend +1
An optical equivalent of the field-programmable gate array (FPGA) is of great interest to large-scale photonic integrated circuits. Previous programmable photonic devices relying o…
Laser-induced Phase-change Perovskite Photodetector Arrays for Optical Information Storage and Imaging
Chen Zou, Jiajiu Zheng, Cheng Chang +2
The reversible phase transition between orthorhombic and cubic phases is demonstrated in all-inorganic perovskite CsPbIBr2 grown by a dual-source vapor-deposition method. The phase…
Ultrathin van der Waals metalenses
Chang-Hua Liu, Jiajiu Zheng, Shane Colburn +4
Ultrathin and flat optical lenses are essential for modern optical imaging, spectroscopy, and energy harvesting. Dielectric metasurfaces comprising nanoscale quasi-periodic resonat…
