Detection of nanoscale objects is highly desirable in various fields such as early‐stage
disease diagnosis, environmental monitoring and homeland security. Optical microcavity …

By virtue of the well‐developed micro‐and nanofabrication technologies and rapidly
progressing surface functionalization strategies, silicon‐based devices have been widely …

We propose and numerically demonstrate the existence of bound state in the continuum
(BIC) in silicon-based one-dimensional photonic crystal nanobeam (1D-PCN). The 1D-PCN …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …

Since the coronavirus pandemic began, research groups worldwide developed diagnostic
tests. One of the promising platforms for testing is an optical and plasmonic biosensor …

Ultrasensitive optical detection of nanometer-scaled particles is highly desirable for
applications in early-stage diagnosis of human diseases, environmental monitoring, and …

The ability to detect nanoscale objects is particular crucial for a wide range of applications,
such as environmental protection, early-stage disease diagnosis and drug discovery …

Current methods to study molecular interactions require labeling the subject molecules with
fluorescent reporters. However, the effect of the fluorescent reporters on molecular dynamics …

We propose and demonstrate a six-hole tapered silicon photonic crystal nanobeam cavity
