A Novel Instrumental Set-Up for In-Situ Detection of Protein Adsorption with Grating Coupler Sensors (GCS)

A Novel Instrumental Set-Up for In-Situ Detection of Protein Adsorption with Grating Coupler Sensors (GCS)

A novel instrumental set-up for the analytical work with grating coupler sensors (GCS) has been investigated. It is shown, that the use of a linearly polarized laser and gratings with small grating periods allows simultaneous excitation of the TE- and TM-modes in the waveguide at almost perpendicula...

Zusammenfassung:A novel instrumental set-up for the analytical work with grating coupler sensors (GCS) has been investigated. It is shown, that the use of a linearly polarized laser and gratings with small grating periods allows simultaneous excitation of the TE- and TM-modes in the waveguide at almost perpendicular incidence.
