Soliton-comb generation in ring-shaped optical Kerr microresonators under thermal effects

open access: yesResults in Optics, 2023
Soliton combs are nonlinear wavetrains resulting from entanglements of localized waves which may be pulse or kink solitons, forming periodic structures called soliton crystals. In this work we examine the possible generation of soliton-comb structures in

Spherical Microresonators [PDF]

open access: yesOptik & Photonik, 2015
AbstractThis article commemorates the 75th birthday of Prof. Dr. techn. Gustav Schweiger and his achievements in this field.Spherical microparticles are characterized by their extraordinary resonance properties. This makes it a promising tool for high sensitive measurements. Furthermore, the dependency on different physical quantities together with the

Model for chaotic dielectric microresonators [PDF]

open access: yesPhysical Review A, 2008
We develop a random-matrix model of two-dimensional dielectric resonators which combines internal wave chaos with the deterministic Fresnel laws for reflection and refraction at the interfaces. The model is used to investigate the statistics of the laser threshold and line width (lifetime and Petermann factor of the resonances) when the resonator is ...

Laser-Induced Graphene on a Quartz Crystal Microbalance for Humidity Sensing

open access: yesCrystals, 2021
In this study, a simple method for synthesizing graphene layer directly on a quartz crystal microbalance (QCM) using a laser was developed. This laser-induced graphene (LIG) was used for sensing surface to simultaneously measure changes in the adsorbed ...

Nonlinear enhanced microresonator gyroscope

open access: yesOptica, 2021
Optical gyroscopes based on the Sagnac effect have been the mainstay of inertial navigation in aerospace and shipping for decades. These gyroscopes are typically realized either as ring-laser gyroscopes (RLGs) or fiber-optic gyroscopes (FOGs). With the recent rapid progress in the field of ultrahigh-quality optical whispering-gallery mode and ring ...
