Efficient Excitation and Tuning of Multi-Fano Resonances with High Q-Factor in All-Dielectric Metasurfaces

open access: yesNanomaterials, 2022
Exciting Fano resonance can improve the quality factor (Q-factor) and enhance the light energy utilization rate of optical devices. However, due to the large inherent loss of metals and the limitation of phase matching, traditional optical devices based ...

Modelling Q-Factors of Micro Pillars [PDF]

open access: yes2007 9th International Conference on Transparent Optical Networks, 2007
The influence of fabrication induced imperfections on quality factors for a microcavity pillar is studied numerically. The dependence on side-wall inclination and etch variations is quantified.

High-Q-Factor Silica-Based Racetrack Microring Resonators

open access: yesPhotonics, 2021
In this paper, ultrahigh-Q factor racetrack microring resonators (MRRs) are demonstrated based on silica planar lightwave circuits (PLCs) platform. A loaded ultrahigh-Q factor Qload of 1.83 × 106 is obtained.

On the q-factorization of power series

open access: yesThe Ramanujan Journal
Any power series with unit constant term can be factored into an infinite product of the form $\prod_{n\geq 1} (1-q^n)^{-a_n}$. We give direct formulas for the exponents $a_n$ in terms of the coefficients of the power series, and vice versa, as sums over partitions. As examples, we prove identities for certain partition enumeration functions.

High-Q-Factor Tunable Silica-Based Microring Resonators

open access: yesPhotonics, 2021
A high-Q-factor tunable silica-based microring resonator (MRR) is demonstrated. To meet the critical-coupling condition, a Mach–Zehnder interferometer (MZI) as the tunable coupler was integrated with a racetrack resonator.

A 5.86 Million Quality Factor Cylindrical Resonator with Improved Structural Design Based on Thermoelastic Dissipation Analysis

open access: yesSensors, 2020
The cylindrical resonator is the core component of cylindrical resonator gyroscopes (CRGs). The quality factor (Q factor) of the resonator is one crucial parameter that determines the performance of the gyroscope. In this paper, the finite element method
