Biomimetic Color Photodetector Developed

A team of researchers from Rice University’s Laboratory for Nanophotonics (LANP) developed a biomimetic color photodetector that responds to red, green, and blue light similar to how the human eye responds to the same colors.

Traditional photodetectors convert light into electrical signals but are not able to differentiate colors. This new device uses interference between the unique plasmonic grating and the photodetector’s surface to direct different colors into the silicon photodetector or reflect it. The use of plasmonic gratings offers a funnel of light into a focused area and the ability to enhance near fields.  The team has used the photodetector as an amplifier, but also as a color filter to increase the amount of light into the detector.
