Nanophotonic sensing has traditionally been driven by maximizing optical sensitivity through stronger field confinement and higher quality factors. However, as devices approach regimes of extreme light-matter interaction, detection performance is increasingly limited not by signal strength but by fluctuations. This rev...

Photonic sensing encompasses technologies at markedly different levels of maturity. Fiber-optic sensing systems are already widely deployed in infrastructure, energy, transportation, and industrial monitoring, whereas many integrated biosensors and plasmonic, metasurface, and wearable platforms remain at laboratory or...

A unified framework for advancing ring resonator biosensors toward stable, reproducible, and application ready sensing systems is established by reframing ring resonator biosensing as a system level problem in which detection capability is fundamentally limited by noise, interfacial processes, and measurement stability...
