BookDOI
Photonic Microresonator Research and Applications
TL;DR: The fundamental principles of operation and notes on Fabrication of Photonic Microresonators can be found in this paper, along with a detailed discussion of the application of these materials in communication and signal processing.
Journal ArticleDOI
Vernier operation of series- coupled optical microring resonator filters
Otto Schwelb,Istvan Frigyes +1 more
TL;DR: In this paper, the tradeoff between coupling coefficients, filter bandwidth, and the suppression of interstitial resonances has been investigated for nonsymmetric Vernier type series-coupled optical microring filters.
Journal ArticleDOI
The nature of spurious mode suppression in extended FSR microring multiplexers
TL;DR: In this paper, a systematic approach to the design of extended free spectral range (FSR) series coupled microring multiplexers is described, which aims to achieve large extension ratios and adequate suppression of the spurious interstitial modes, while moderating radiation enhancing ring diameter reduction as much as possible.
Journal ArticleDOI
A design for a high finesse parallel‐coupled microring resonator filter
Otto Schwelb,Istvan Frigyes +1 more
TL;DR: In this paper, the interaction between the circulating waves in microrings and the connecting busbars provides two parallel-coupled MCs with filter characteristics that feature a stopband with uniformly large rejection and high finesse.
Journal ArticleDOI
Crosstalk and bandwidth of lossy microring add/drop multiplexers
TL;DR: Performance characteristics and the design for optimum crosstalk suppression and extended bandwidth are described for lossy microring add/drop multiplexers.
