Laser with Imperfections Emits in All Directions (IMAGE)
Caption
The left panel correspond to a 'good' nanolaser, while the right panel to a disordered nanolaser. The upper images are photographs of the nanolasers made with an electron microscope. The light grey areas correspond to silver nanoparticles acting as the nano-mirrors of the laser. The lower panels correspond to the light emission from the nanolasers as a function of the emitted angle and wavelength (color of the emission). For the good laser (bottom left), the light is emitted in one direction and has one color. For the disordered nanolaser, the emission has also one color, but it is now omnidirectional.
