Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Harnessing the full complexity of optical fields requires the complete control of all degrees of
freedom within a region of space and time—an open goal for present-day spatial light …

An approach to optimizing the Q factors of two-dimensional photonic crystal (2D-PC)
nanocavities based on deep learning is hereby proposed and demonstrated. We prepare a …

Photonic crystal nanocavities that simultaneously possess small modal volumes and high
quality (Q) factors have opened up novel research areas in photonics during this decade …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

This review covers photonic crystal cavities (PCCs) and their applications in optical sensors,
with a particular focus on the structures of different PCCs. For each kind of optical sensor …

The application of novel technologies to silicon electronics has been intensively studied with
a view to overcoming the physical limitations of Moore's law, that is, the observation that the …

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
light–matter interaction. This article reviews the current status of this subject, including both …

Enhancing light–matter interaction is a key requisite in the realm of optical sensors. Bound
states in the continuum (BICs), possessing high quality factors (Q factors), have shown great …
