As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

This book is all about integrated ring resonators made out of optical waveguides in various
materials for different applications. Integrated ring resonators are used to build optical filters …

This chapter reviews the fundamental optical properties and applications of photonic
molecules (PMs)–photonic structures formed by electromagnetic coupling of two or more …

One of the first papers to deal about the simulation of an integrated ring resonator for a
bandpass filter has been published in 1969 by EA Marcatili. This can be regarded as the …

We propose a two-ring resonator configuration that can provide optical switching with high
extinction ratio (ER), large modulation depth (MD) and low switching threshold, and …

Optical micro-resonators have broad applications. They are used, for example, to enhance
light–matter interactions in optical sensors or as model systems for investigating …

Photonic systems based on microring resonators have a fundamental constraint given by the
strict relationship among free spectral range, total quality factor QT, and resonator size …

We report on coupling of two whispering gallery mode resonators in the Terahertz frequency
range. Due to the long wavelength in the millimeter to submillimeter range, the resonators …

The reflection properties of a coupled-ring reflector (CRR) are analyzed using the transfer
matrix method. The CRR is composed of two coupled rings that are coupled to a bus …

We present analysis and design of microring resonators integrated with reflective elements
to obtain custom wavelength-selective devices. We introduce a graphical method that …
