Scalable photonic crystal waveguides with 2 dB component loss
Yahui Xiao, Feifan Wang, Dun Mao +5
Periodic or gradient subwavelength structures are basic configurations of photonic crystals and metamaterials. The measured linear losses of those nanophotonic devices are well-bey…

Engineering the light coupling between metalens and photonic crystal resonators for robust on-chip microsystems
Yahui Xiao, Zi Wang, Feifan Wang +3
We designed an on-chip transformative optic system of a metalens-photonic crystal resonator metasystem on a foundry compatible silicon photonic platform. By adjusting the on-chip m…
