Microring resonator channel dropping filters
TL;DR: In this article, a method of coupling of modes in time was proposed to simplify both the analysis and filter synthesis aspects of these devices, and the response of filters comprised of an arbitrarily large dumber of resonators may be written down by inspection, as a continued fraction.

An eight-channel add-drop filter using vertically coupled microring resonators over a cross grid
TL;DR: In this article, an eight-channel add-drop cross-grid vertically coupled microring resonator (VCMRR) filter is proposed and demonstrated, which achieves a free-spectral range of 20 nm and optical bandwidth of 1 nm, while changes of the radii in increments of 50 nm lead to a nominal channel spacing of 5.7 nm.
