Wavelength tuning and stabilization of microring-based filters using silicon in-resonator photoconductive heaters.

TL;DR: In this paper, n-doped resistive heaters in silicon waveguides were used to automatically tune and stabilize the filter's resonance wavelength to the input laser's wavelength, without requiring dedicated defect implantations, additional material depositions, dedicated photodetectors, or optical power tap-outs.
Journal ArticleDOI

Federated learning enables big data for rare cancer boundary detection

Sarthak Pati, +278 more
TL;DR: This paper presented the largest FL study to date, involving data from 71 sites across 6 continents, to generate an automatic tumor boundary detector for the rare disease of glioblastoma, reporting the largest such dataset in the literature.
Journal ArticleDOI

Wavelength tuning and stabilization of microring-based filters using silicon in-resonator photoconductive heaters

TL;DR: It is demonstrated that n-doped resistive heaters in silicon waveguides show photoconductive effects with high responsivities and theoretically show that series-coupled MRR-based filters of any order can be automatically tuned by using photoconductor heaters to monitor the light intensity in each MRR, and sequentially aligning the resonance of eachMRR to the laser's wavelength.
Journal ArticleDOI

Acoustic Shadow Detection: Study and Statistics of B-Mode and Radiofrequency Data.

TL;DR: The high accuracy in different imaging scenarios indicates that the shadows can be detected with high versatility and without expert configuration, and can be used for more specialized techniques to be developed for specific applications in the future.
Proceedings ArticleDOI

Silicon photonic polarization receiver with automated stabilization for arbitrary input polarizations

TL;DR: In this paper, the authors demonstrate an automated polarization receiver that couples light from any polarization state output from a singlemode fiber into the fundamental quasi-TE mode of a single-mode waveguide in an integrated silicon photonic circuit.
