Researchers at Stanford have developed a tunable metasurface with high reflectance and large phase modulation for use as optical phase modulators or beam steering device (Lidar). Currently, the large size of beam steering devices is a critical problem.
Researchers at Stanford have developed a multi-wavelength laser with perpendicular polarization, which supports easy and independent measurement in various optical sensors for improved accuracy and speed.
Researchers in the Dionne group at Stanford have designed a nanoscale laser capable of self-isolated Raman Lasing, where lasing and isolation occurs within the same pumping mechanism.
The Dionne lab has developed ultrathin and compact devices for electrically driven beamsteering that fit on a semiconductor chip. These devices rely on resonant dielectric nanostructured surfaces known as "high quality factor" (high-Q) metasurfaces.
Stanford researchers have developed a novel tomographic technique, cathodoluminescence (CL) spectroscopic tomography, to probe optical properties in 3D with nanometer-scale spatial and spectral resolution.
