  • Devices, systems and methods for ultrafast optical applications
    Patent number: 9658510
    Abstract: An optical device capable of an ultrafast and large change of its reflection or absorption coefficient upon being excited by an ultrafast optical pulse with wavelength in the visible, near-infrared, or infrared spectral regions. The optical device includes, in sequential order, a first thick metallic layer, a first dielectric layer, a second thin metallic layer, and a second dielectric layer. The optical device acts as a nonlinear mirror that presents a large reflectance at low irradiance and a low reflectance at large irradiance. The optical device can further act as a nonlinear mirror that presents a linear and nonlinear reflectance with a large angular bandwidth.
    Type: Grant
