Abstract The development of memory devices with functions that simultaneously process and store data is required for efficient computation. To achieve this, artificial synaptic devices have been proposed because they can construct hybrid networks wit

Though laser action has been reported for optical bound states in the continuum (BIC) cavities with high quality factors, these BIC lasers lacked practical applicability. Here, the authors report an ultralow-threshold super-BIC laser featuring merged

The RAS-RAF-ERK1/2 pathway is a crucial target for anticancer drug development because of the high prevalence of ERK activation in human cancers. Mitogen-activated protein kinases (MAPKs) are pivotal intracellular cascade molecules critical in all eu

High quality factor and small mode volume in nanocavities enable the demonstration of efficient nanophotonic devices with low power consumption, strong nonlinearity, and high modulation speed, due to the strong light-matter interaction. In this revie

We study multiphoton photoluminescence from several types of nonlinear resonant metaphotonic structures. We develop a general theoretical approach to describe such nonlinear effects and confirm our predictions in experiments with perovskite metasurfa
