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 …

The vast majority of work on waveguide-coupled resonators focuses on decreasing losses in
the waveguide and coupling region. Here we present fully integrated resonators based on …

High-Q silicon nitride (SiN) microresonators enable optical Kerr frequency comb generation
on a photonic chip and have recently been shown to support fully coherent combs based on …

The further development of “lab on fiber” technology demands more powerful optical
microsystems and optical fibers with special functions to create sensors with better …

Corresponding to the different phase‐shifts of the interference modes, the whispering gallery
mode resonator‐based Fano resonance exhibits a variety of unique spectral lineshapes that …

Integrated Raman lasers have been well explored using silica and silicon platforms for
decades. A well‐known equation with negligible nonlinear losses is employed for …

In this paper, multiple Fano resonances based on semi-ring-rectangular composite cavity
(SRRCC) structure are numerically investigated and explained by the finite-difference time …

Narrowband microwave photonic filters based on a microring resonator are difficult to
achieve because low cavity loss and low coupling loss should be satisfied simultaneously …

Rare-earth ions in solids are of particular interest for quantum information storage and
processing because of the long coherence times of the 4f states 1. In the past few years …

We achieved enhanced Fano resonance by coupling a bottle resonator with a special non-
adiabatic tapered fiber, where there is a high intensity distribution ratio between high-order …
