Investigation of Q degradation in low-loss Si3N4 from heterogeneous laser integration

Posted by dbos UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Joel Guo, Chao Xiang, Warren Jin, Jonathan Peters, Mingxiao Li | Summary: High-performance, high-volume-manufacturing Si3N4 photonics requires extremely low waveguide losses augmented with heterogeneously integrated lasers for applications beyond traditional markets of high-capacity interconnects. State-of-the-art quality factors (Q) over 200 million at 1550 nm have been […]

The polarization hierarchy for polynomial optimization over convex bodies, with applications to nonnegative matrix rank

Posted by dbos UCSB

Kavli Affiliate: David Gross | First 5 Authors: Martin Plávala, Laurens T. Ligthart, David Gross, , | Summary: We construct a convergent family of outer approximations for the problem of optimizing polynomial functions over convex bodies subject to polynomial constraints. This is achieved by generalizing the polarization hierarchy, which has previously been introduced for the […]

A likelihood-based sensitivity analysis for addressing publication bias in meta-analysis of diagnostic studies using exact likelihood

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Taojun Hu, Yi Zhou, Xiao-Hua Zhou, Satoshi Hattori, | Summary: Publication bias (PB) poses a significant threat to meta-analysis, as studies yielding notable results are more likely to be published in scientific journals. Sensitivity analysis provides a flexible method to address PB and to examine the impact […]
