Researchers in Prof. Mark Brongersma's laboratory have engineered a novel patterning scheme for semiconductor nanowires to increase their photon absorption in thin films for solar cells and photo-detectors.
Stanford researchers have developed a high efficiency OLED device by nanopatterning the electrode layer to create a high impedance metasurface (HIM) that reduces 'plasmonic' losses. A typical metal cathode traps a large portion of generated light in an OLED.
Stanford inventors have developed a method that allows for simultaneous 3D imaging with high resolution by using a multifunctional metalens to replace the conventionally used microlens array in light-field imaging.
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.
Researchers at Stanford have developed a simpler and low-cost micro-cavity design for color tuning of organic light emitting devices (OLEDs) for display applications. A micro-cavity is an essential part of OLED display for high color purity.
Active manipulation of light beams is required for a range of emerging optical technologies, including sensing, optical computing, virtual/augmented reality, dynamic holography, and computational imaging.
