“…Extinction Ratio Modified by Reflection Inside the MRR tCMT has been used intensively to analyze a ring resonator with or without reflection [18,[20][21][22]. We will first use tCMT to build a model for an ideal MRR and then build a model for an MRR with reflection inside, to clearly and quantitatively show how the reflection will influence the performance (resonance wavelength, extinction ratio, etc.)…”

We present a novel and simple method to obtain an ultrawide free spectral range (FSR) silicon ring resonator together with a tuning range covering the entire spectrum from 1500 to 1600 nm. A ring resonator with a large FSR together with a high Q factor, high tuning efficiency, and low fabrication cost and complexity is desired for many applications. In this paper, we introduce a novel way to make such a ring resonator, which takes advantage of the well-known resonance-splitting phenomenon. It is a single ring resonator with an FSR of more than 150 nm around 1550 nm and which has an easy thermo-optic tunability that can produce a tuning range around 90 nm or even more. Moreover, the device is simple to implement and can be fabricated in standard complementary metal-oxide semiconductor technology without requiring any kind of complicated processing or extra materials. The potential applications include single mode laser cavities, wavelength division multiplexing filters, (de)multiplexers, optical sensors, and integrated reflectors.

“…Otherwise the multiring configuration can result in a split resonance. Beside, the tuning efficiency is relatively poor and the resonance mode is hard to move continuously in the spectrum; moreover, the well-known problem of backscattering induced splitting is not considered and cannot be compensated [18].…”

A simple and novel method to make a silicon ring resonator without the limit of free spectral range (FSR) is presented. For many applications, a ring resonator is desired with an ultra-wide FSR, a high quality factor, a large extinction ratio and low-fabrication complexity. In this paper we propose a novel method to obtain such a ring resonator, which is a single all-silicon microring with a FSR as large as 150 nm around 1550 nm. It's based on the well-known phenomenon of resonance splitting.

Experimentally demonstrate the origin for asymmetric resonance splitting and contributions from couplers to backscattering in SOI microrings

Abstract: Abstract:We build a new fitting method which could fit all kinds of resonances of microrings. With that, we experimentally demonstrate the cause for asymmetrically split resonances as well as couplers induced backscattering in SOI microrings.
