OPTICAL SENSOR |
| 摘要 |
An embodiment of the invention relates to an optical sensor for detecting chemical, biochemical or biological substances, the sensor comprising a laser and a semiconductor chip,
wherein at least one photodetector and at least one high-contrast grating are monolithically integrated in said same chip,wherein the high-contrast grating is configured to optically couple radiation emitted by the laser into the photodetector, andwherein the coupling behaviour of said high-contrast grating depends on the optical properties of external substances that are brought near to or in contact with the high-contrast grating. |
