INTEGRATED POLARIZED LIGHT EMITTING DIODE WITH A BUILT-IN ROTATOR

This technology provides an LED design that can greatly improve polarization selectivity, 10:1, resulting in greater efficiency of the LED. The technology lies within a photonic crystal bi-refringent polarization rotator and an oxide spacer. The design blue-shifts transmission, which greatly improves overall efficiency of the LED by recycling wasted light and increasing polarization selectivity. Applications include: backlight units of liquid crystal displays, low noise sensing and high-contrast bio-imaging.

EFFICIENT AND DIRECTED NANO-LIGHT EMITTING DIODE, AND METHOD FOR MAKING SAME

This technology relates to an ultra high efficient LED system with the capability to modify an LEDs radiation pattern by changing its physical dimension-emission beam shape. The ultra high efficiency and redistribution of light has been achieved without the use of a back reflector. The ultra high efficiency can be controlled by changing the size of the nanorods within the design. These features can be very useful for bio-sensing and bio-imaging applications.
