| An optical micrograph of an array of GeOI photodetectors. The active areas appear colored when held at an angle to the illuminating light because the interdigitated fingers of the devices are of a similar size to visible wavelengths. The detectors at the top of the photograph are 100 µm wide, while those at the bottom measure just 10 µm. (Credit: IBM) |
