A hybrid optics platform consisting of waveguides vertically coupled to high-index-contrast waveguides can provide tight bend radii for ring resonators and strong tuning capability via electrical-optic effects in substrate. A vertically integrated ring resonator having an ultranarrow free spectral range (FSR)...
A vertically integrated As2S3 ring resonator side-coupled to Ti:LiNbO3 waveguide was designed and fabricated. We have demonstrated an ultra-high Q value of 3.5×105 and low propagation loss of 1.2 dB/cm over a 1.7 cm race-track ring resonator.
A race-track ring resonator with a 600 mum diameter and 25 GHz free spectral range is demonstrated by vertically integrating arsenic-trisulfide (As2S3) waveguides with Ti-diffused LiNbO3 waveguides. Measurements of the TM ring resonator response are presented.
Quantitative simultaneous monitoring of the expression levels of thousands of genes under various experimental conditions is now possible using microarrays. However, there are still gaps toward whole-genome functional annotation of genes using gene expression data. In this paper, we propose a novel technique called fuzzy nearest clusters for functional annotation of unclassified genes. The technique...
