The video demonstration shows how the laser light is incoupled into the planar waveguide when the optical grating is illuminated at a certain, resonance angle of incident. More detail about the label free biosensor: http://www.owls-sensors.com
Is that a thin film you are coupling light into? How to find this resonance angle?
