Electrically reconfigurable nonvolatile flatband absorbers in the mid-infrared with wide spectral tuning range
Romil Audhkhasi, Virat Tara, Matthew Klein +5
While recent advances in reconfigurable photonics have provided new avenues for manipulating light on the subwavelength scale, on-demand control of infrared absorption remains elus…
Low-power 7-bit hybrid volatile/ nonvolatile tuning of ring resonators
Jayita Dutta, Rui Chen, Virat Tara +1
Programmable photonic integrated circuits are expected to play an increasingly important role to enable high-bandwidth optical interconnects, and large-scale in-memory computing as…
Pixelated Bayer Spectral Router Based on Sparse Meta-atom Array
Yifan Shao, Rui Chen, Yubo Wang +4
It has long been a challenging task to improve the light collection efficiency of conventional image sensors built with color filters that inevitably cause the energy loss of out-o…
Low-loss multilevel operation using lossy PCM-integrated silicon photonics
Rui Chen, Virat Tara, Jayita Dutta +3
Chalcogenide phase-change materials (PCMs) offer new paradigms for programmable photonic integrated circuits (PICs) thanks to their zero static energy and significant refractive in…
