Reseachers Create First Integrated Circularly Polarized Light Detector on a Silicon Chip

What do you get when you combine some biomimicry , metamaterials and nanowires ? It turns out to be the first integrated circularly polarized light detector on a silicon chip. Its development could usher in a new generation of portable sensors that can use polarized light for applications ranging from drug screening to quantum computing. Researchers at Vanderbilt University have used silver nanowires to fabricate a metamaterial that is capable of detecting polarized light in a way not unlike the way cuttlefish, bees, or mantis shrimp do it. “Although it is largely invisible to human vision, the polarization state of light can provide a lot of valuable information,” said assistant professor Jason Valentine in a press release. “However, the traditional way of detecting it requires several optical elements that are quite bulky and difficult to miniaturize. We have managed to ...
