Shrinking the footprint of IR photodetectors

Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. To date, however, IR detectors have relied on bulky, high-cost materials and technologies. The trend toward ultracompact designs is supported by the development of a cost-effective miniaturization process for IR spectrometers based on a quantum dot photodetector, which can be integrated on a single chip.
