Point-of-care diagnostic devices typically require six distinct qualities: they must deliver at least the same sensitivity and selectivity, and for a cost per assay no greater than that of today's central lab technologies, deliver results in a short period of time (<;15 min at GP; <;2h in hospital), be portable or at least small in scale, and require no or extremely little sample preparation...
The experimental demonstration of a high efficiency silicon nitride grating coupler is reported for wavelengths from lambda = 1.25 to 1.45 mum for TE polarization. At the resonant angle, a coupling efficiency higher than 60% has been measured.
