Diffraction Grating with Multiple Periodic Widths |
| 摘要 |
An integrated circuit includes a substrate, a plurality of photo detectors formed in the substrate, and a diffraction grating having multiple sections disposed over the plurality of photo detectors. Each section of the diffraction grating has a respective periodic width for a respective target wavelength. The diffraction grating has at least two different target wavelengths. The diffraction grating is interlaced with filters. The filters in each section of the diffraction grating are configured to pass a respective electromagnetic wave with the respective target wavelength. |
