Reducing Insertion Loss of Wavelength-Routed Optical Network Based on Microring Resonator Optical Switches

Duobinary Modulation Format in Optical Communication Systems

This paper presents the environment of the optical fiber and digital information transmission over optical fiber, using signal transformation technique called duobinary modulation technique. We propose a complete duobinary encoder and duobinary decoder that we tested in Matlab simulink R2014B. In the final part, it will be shown a comparison of duobinary modulation technique with on-off keying ...

HCMT models of optical microring-resonator circuits

1 Ringresonator modelling Optical microresonator circuits [1, 2, 3] are considered, consisting of a number of not necessarily identical circular cavities and straight waveguides, with evanescent wave interaction between these elements. A simple configuration with a single cavity and two straight bus waveguides serves as an example to explain the frequency-domain Hybrid analytical/numerical Coup...

Biosensing Using Microring Resonator Interferograms

Optical low-coherence interferometry (OLCI) takes advantage of the variation in refractive index in silicon-wire microring resonator (MRR) effective lengths to perform glucose biosensing using MRR interferograms. The MRR quality factor (Q), proportional to the effective length, could be improved using the silicon-wire propagation loss and coupling ratio from the MRR coupler. Our study showed th...
