Abstract: An optical biosensor, and a method of manufacturing the same, includes a first layer, a second layer stacked on the first layer, a first grating coupler within the first layer and the second layer, and a second grating coupler within the first layer. The first grating coupler is configured to couple a light pattern provided to a front side of the optical biosensor. The second grating coupler is configured to output the light pattern coupled by the first grating coupler to a photoelectric conversion element on a rear side of the optical biosensor.
