โœฆ Synopsis

In terms of the coupled mode theory and transfer matrix technique, novel formulas of the amplitude coupling ratios and transfer functions are presented for a series-coupled microring resonator (MRR) array. By using these formulas, parameters are optimized, and transmission characteristics including the transmission spectrum and the insertion loss are analyzed for a SiN/SiO 2 series-coupled MRR array on Si substrate. The box-like spectral response is successfully obtained owing to the proper selection of the amplitude coupling ratio between the channel and the ring, and that between adjacent rings, as well as the number of series-coupled rings.

## Abstract For narrower wavelength spacing in order to allow a further increase of communication capacity for optical communications, interleavers are used in addition to wavelength multiplexer/demultiplexers. The wavelength filters for an interleaver are required to have characteristics in which
