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.
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.
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.
