Preventing overfitting in infrared ellipsometry using temperature dependence: fused silica as a case study
Shenwei Yin, Jin-Woo Cho, Demeng Feng +6
Fitting oscillator models to variable-angle spectroscopic ellipsometry (VASE) data can lead to non-unique, unphysical results. We demonstrate using temperature-dependent trends to…

Broadband light extraction from near-surface NV centers using crystalline-silicon antennas
Minjeong Kim, Maryam Zahedian, Wenxin Wu +9
We use crystalline silicon (Si) antennas to efficiently extract broadband single-photon fluorescence from shallow nitrogen-vacancy (NV) centers in diamond into free space. Our desi…

Self-referencing photothermal common-path interferometry to measure absorption of Si3N4 membranes for laser-light sails
Tanuj Kumar, Demeng Feng, Shenwei Yin +12
Laser-light sails are a spacecraft concept wherein lightweight "sails" are propelled by high-intensity lasers. We investigated the near-infrared absorption of free-standing membran…
