Prepolarized MRI shows quality MRI images near stainless steel implants. I also will present a novel susceptibility matching material that is soft, safe, RF compatible, and conforming to the...

BSAC Seminar: Light Extraction from Photonic Crystal LEDs

February 2, 2010
Mischa Megens BSAC Staff Engineer February 2, 2010 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Bernhard Boser

Photonic crystal structures are well known for their capacity to influence spontaneous emission, and it has been suggested that such structures could enhance efficiency and beam shaping of LEDs. To achieve such improvements, GaN PXLEDs have been made at Philips LumiLEDs in an effort to measure, understand and accurately predict their emission patterns. Successful application of such technology requires a method to fabricate photonic crystal structures...
