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 …

So far, nanostructuring of hard optical crystals has been exclusively limited to their surface,
as stress-induced crack formation and propagation render high-precision volume processes …

Nonlinearity in complex systems leads to pattern formation through fundamental interactions
between components. With integrated photonics, precision control of nonlinearity explores …

We introduce a photonic crystal ring cavity that resembles an internal gear and unites
photonic crystal (PhC) and whispering gallery mode (WGM) concepts. This …

A label-free optical biosensor based on a one-dimensional photonic crystal microring
resonator with enhanced light-matter interaction is demonstrated. More than a 2-fold …

We experimentally demonstrate a compact broadband polarization beam splitter (PBS)
based on a multimode interference (MMI) coupler with internal photonic crystal (PC) for the …

A comprehensive electromagnetic mathematical model of an ultra-high Q-factor 1D-PhC ring
resonator (1D-PhCRR) is proposed. The 1D-PhCRR results by the integration of a 1D-PhC …

A compact grating double-slot micro-ring resonator (GDSMRR) based on an SOI platform
with a footprint of less than 11 μ m× 11 μ m is analyzed and proposed in order to achieve a …

Integrated mid-infrared sensing offers opportunities for the compact, selective, label-free and
non-invasive detection of the absorption fingerprints of many chemical compounds, which is …

We design and experimentally demonstrate a broadband 1310/1550 nm wavelength
demultiplexer based on a multimode interference coupler with a tapered internal photonic …
