High-dimensional frequency crystals and quantum walks in electro-optic microcombs
Christian Reimer, Yaowen Hu, Amirhassan Shams-Ansari +2
Synthetic optical structures have enabled studies of various physical processes and discoveries of new phenomena in a controllable manner. Past realizations, using for example coup…
Microwave-to-optical conversion using lithium niobate thin-film acoustic resonators
Linbo Shao, Mengjie Yu, Smarak Maity +8
We demonstrate conversion of up to 4.5 GHz-frequency microwaves to 1500 nm-wavelength light using optomechanical interactions on suspended thin-film lithium niobate. Our method uti…
Supercontinuum generation in angle-etched diamond waveguides
Amirhassan Shams-Ansari, Pawel Latawiec, Yoshitomo Okawachi +8
We experimentally demonstrate on-chip supercontinuum generation in the visible region in angle etched diamond waveguides. We measure an output spectrum spanning 670 nm to 920 nm in…
Ultra-low loss integrated visible photonics using thin-film lithium niobate
Boris Desiatov, Amirhassan Shams-Ansari, Mian Zhang +2
Integrated photonics is a powerful platform that can improve the performance and stability of optical systems, while providing low-cost, small-footprint and scalable alternatives t…
Low-loss fiber-to-chip interface for lithium niobate photonic integrated circuits
Lingyan He, Mian Zhang, Amirhassan Shams-Ansari +3
Integrated lithium niobate (LN) photonic circuits have recently emerged as a promising candidate for advanced photonic functions such as high-speed modulation, nonlinear frequency…
Phononic band structure engineering for high-Q gigahertz surface acoustic wave resonators on lithium niobate
Linbo Shao, Smarak Maity, Lu Zheng +9
Phonons at gigahertz frequencies interact with electrons, photons, and atomic systems in solids, and therefore have extensive applications in signal processing, sensing, and quantu…
