Broadband picometer-scale resolution on-chip spectrometer with reconfigurable photonics
We propose an on-chip spectrometer design that leverages reconfigurable networks with distributed broadband filters, demonstrating a 30 pm resolution over a 115 nm bandwidth that can be readily scaled further.

Tbit/s line-rate satellite feeder links enabled by coherent modulation and full-adaptive optics
This paper demonstrates a 53 km free-space-optical communication link mimicking a satellite-downlink. It achieves 1Tbit/s transmission by addressing turbulence and low-SNR issues through adaptive optics and a novel four-dimensional modulation format.
