We present the design, fabrication, and characterization of submicronic grating couplers integrated on Si3N4 A Crítica ao Cinema Brasileiro Atual: a retórica das revistas Veja e Bravo! rib waveguide Mach-Zehnder interferometers (MZIs) for biosensing applications working in the visible spectral range for both TE and TM polarizations.Depending on the waveguide structure, a maximum of 11.5% of coupling efficiency has been experimentally obtained at 658 nm, while a limit of detection of 1.6 × 10-7 in refractive index unit is achieved for the biosensor.

These results represent an important milestone toward the achievement of a truly Feline Stool-Associated Circular DNA Virus (FeSCV) in Diarrheic Cats in China portable and multiplexed point-of-care platform using the integrated MZI sensor.
