As part of a comprehensive optofluidic platform, researchers at Stanford have developed an integrated dynamic flat-optics system that supports unprecedented compact configurations.
As part of a comprehensive optofluidic platform, researchers at Stanford have developed a new type of reflective display technology for achieving transparent displays, which allow users to receive visual information from the external world through the display at the same time.
Researchers at Stanford have developed an ultracompact, high-quality-factor (high-Q) metasurface that enables more convenient phase contrast imaging. Phase contrast imaging is a critical technique in biology and medicine to image essentially transparent objects such as cells.
Researchers at Stanford have developed a near-eye display enabling both Augmented Reality (AR) and Virtual Reality (VR) modes with dynamically controlled contrast.
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 dielectric diffraction grating that provides high (near-unity) diffraction efficiencies in an ultra-compact volume.
Stanford researchers have developed a simple optical device for low-power, active light tuning. The device tunes the color of light across the visible spectrum and at select wavelengths by electrical biasing an array of micron sized pixels or nanowires.
Stanford researchers have developed an optical coating that steers infrared and visual light in different paths while suppressing the typical undesired rainbow effect.
