A validated lumped-element model for bioinspired acoustic flow sensing toward the performance limit
Wei Sun, Wanyin Zheng, Xiangyu Wei +3
Flow sensing is fundamental to both biological survival and technological innovation. Inspired by biological mechanoreceptors, artificial flow sensors detect subtle fluid motion us…
All-passive upconversion of incoherent near-infrared light at intensities down to 10 W/cm
Rabeeya Hamid, Demeng Feng, Pournima Narayanan +10
Frequency upconversion, which converts low-energy photons into higher-energy ones, typically requires intense coherent illumination to drive nonlinear processes or the use of exter…
Enhanced biochemical sensing with high-Q transmission resonances in free-standing membrane metasurfaces
Samir Rosas, Wihan Adi, Aidana Beisenova +7
Optical metasurfaces provide novel solutions to label-free biochemical sensing by localizing light resonantly beyond the diffraction limit, thereby selectively enhancing light-matt…
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…
