Brightly Colored Bird Feathers Inspire New Kind of Laser - 0 views

Paige Poisson on 09 May 11This article is a very interesting example of biomimicry. It reminds me a lot of how we mimic butterfly wings to produce iridescence. This article talks about how physicist Hui Cao from Yale was inspired by birghtly colored bird feathers to create a new type of laser. Just like butterfly wings, the color on the birds' feathers are the result of texture on a nano scale. These brightly colored birds have organized air pockets that reflect light in a certain way. Cao used this to make air pockets in a thin sheet of gallium arsenide. This proved to be effective in creating a cheap, efficient laser light. While he does not have any applications for this yet, it is a great use of nature to start to solve current problems with technology.
