Nanolaser Inspired by Nature Changes Colors Like a Chameleon

Facebook X LinkedIn Email
A new nanolaser, with a design inspired by nature, can change color using the same nanomechanics that a chameleon uses. A chameleon changes color by controlling the spacing of nanocrystals on its skin. The nanolaser exploits periodic arrays of metal nanoparticles on a stretchable, polymer matrix in a similar way. As the matrix either stretches to pull the nanoparticles farther apart or contracts to push them closer together, the wavelength of the laser changes, which in turn changes the color of light it emits. A new nanolaser leverages the same color-changing mechanism that a...Read full article

    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
